You have an aquarium in the shape of a rectangular prism. The base is 4 feet by 3 feet. The height is 2 feet. How many square feet of glass were used to build the aquarium? (The top of the aquarium is open.)

there are two pairs of rectangular faces on the sides, right? So the area is

4*3 + 2(4*2 + 3*2) = _____ ft^2

so its 40

someone plz answer

thank u :)

To find the amount of glass used to build the aquarium, we need to calculate the surface area of all six sides of the rectangular prism. Since the top of the aquarium is open, we only need to consider the remaining five sides.

Step 1: Calculate the area of the base
The base of the aquarium is a rectangle with dimensions 4 feet by 3 feet. To find the area, multiply the length by the width:
Base area = 4 feet * 3 feet = 12 square feet

Step 2: Calculate the area of the remaining four sides
The remaining four sides of the rectangular prism are all rectangles with dimensions equal to the height of the aquarium (2 feet) and the lengths and widths of the base. Since the opposite sides have the same dimensions, we only need to calculate the area of one side and then multiply by 2 to get the total for both.

Side area = 2 feet * 4 feet = 8 square feet
Total area for the four sides = Side area * 2 = 8 square feet * 2 = 16 square feet

Step 3: Add up the areas of the base and the remaining four sides
Total glass area = Base area + Total area for the four sides
= 12 square feet + 16 square feet
= 28 square feet

Therefore, the aquarium required 28 square feet of glass to build.
