Tommy and Cole are planning to build an aquarium for their pet fish them in the dimensions of the aquarium or 17 inches long 9 inches wide and 11 inches tall how much glass do they need to buy to enclose the aquarium
Surface area = 2(L x W) + 2(L x H) + 2(W x H)
Surface area = 2(17 x 9) + 2(17 x 11) + 2(9 x 11)
Surface area = 306 + 374 + 198
Surface area = 878 square inches
Therefore, Tommy and Cole need to buy 878 square inches of glass to enclose the aquarium.
To find the surface area of the room, including the floor and ceiling that needs to be painted, we need to calculate the area of the six faces of the rectangular solid.
Area of Floor = Length x Width = 20 ft x 15 ft = 300 square feet
Area of Ceiling = Length x Width = 20 ft x 15 ft = 300 square feet
Area of Front Wall = Length x Height = 20 ft x 9 ft = 180 square feet
Area of Back Wall = Length x Height = 20 ft x 9 ft = 180 square feet
Area of Left Wall = Width x Height = 15 ft x 9 ft = 135 square feet
Area of Right Wall = Width x Height = 15 ft x 9 ft = 135 square feet
Total Surface Area = Area of Floor + Area of Ceiling + Area of Four Walls
Total Surface Area = 300 + 300 + 180 + 180 + 135 + 135
Total Surface Area = 1230 square feet
Therefore, the surface area of the room that needs to be painted, including the floor and ceiling, is 1230 square feet.
There you go! <3 Well I have to go now. TY for helping me.

Manny created a storage bin for the family to hold the remote control and cell phone cords. What is the total surface area of the storage bin?
(1 point)
surface area = ___cm2
The total surface area of the cuboid can be calculated using the formula:
Surface area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height of the cuboid.
From the given image, we can see that all three dimensions of the cuboid are 5 centimeters.
Substituting the values in the formula, we get:
Surface area = 2 x 5 x 5 + 2 x 5 x 5 + 2 x 5 x 5
Surface area = 50 square centimeters
Therefore, the total surface area of the storage bin created by Manny is 50 square centimeters.

surface area = ___square feet
Christian collects model cars and planes. He has a display showcase of all of his collectors' items. Solve this real-world problem to find the surface area of the display showcase if it is the shape of a triangular prism with the following dimensions: h=9 inches, b=17 inches, s1=10 inches, s2
=12 inches, s3
= 17 and l=10 inches.(1 point)
S.A.=__in.2
The surface area of a triangular prism can be found by first calculating the area of the two triangular bases and then adding the area of the three rectangular faces.
The area of the two triangular bases can be calculated using the formula:
Area of Triangle = (1/2) x base x height
Where base and height are the dimensions of the base of the triangle.
Base of Triangle 1 = s1 = 10 inches
Height of Triangle 1 = l = 10 inches
Area of Triangle 1 = (1/2) x 10 inches x 10 inches = 50 square inches
Base of Triangle 2 = s3 = 17 inches
Height of Triangle 2 = l = 10 inches
Area of Triangle 2 = (1/2) x 17 inches x 10 inches = 85 square inches
Total area of the two triangular bases = 50 + 85 = 135 square inches
Next, we need to calculate the area of the three rectangular faces.
Face 1: Length = s1 = 10 inches, Height = h = 9 inches
Area of Face 1 = s1 x h = 10 inches x 9 inches = 90 square inches
Face 2: Length = s2 = 12 inches, Height = h = 9 inches
Area of Face 2 = s2 x h = 12 inches x 9 inches = 108 square inches
Face 3: Length = s3 = 17 inches, Height = h = 9 inches
Area of Face 3 = s3 x h = 17 inches x 9 inches = 153 square inches
Total area of the three rectangular faces = 90 + 108 + 153 = 351 square inches
Total surface area = 2(Triangular Base Area) + 3(Rectangular Face Area)
Total surface area = 2(135 square inches) + 3(351 square inches)
Total surface area = 270 + 1053
Total surface area = 1323 square inches
Therefore, the surface area of the display showcase is 1323 square inches.
