a rectangle box has H= 6 on the right corner and L=12 on the bottom right,
and W=9 is on the left bottom side.
Determine the area of the top of the rectangular prism_____
Determine the area of the side of the rectangular prism_____
Determine the area of the front of the rectangular prism_____
What is the total surface area of the rectangular prism_____
To find the area of the top of the rectangular prism, we use the formula for the area of a rectangle: A = L x W.
A = 12 x 9 = 108 square units
To find the area of the side of the rectangular prism, we use the formula for the area of a rectangle: A = H x W.
A = 6 x 9 = 54 square units
To find the area of the front of the rectangular prism, we use the formula for the area of a rectangle: A = H x L.
A = 6 x 12 = 72 square units
The total surface area of the rectangular prism is the sum of all the individual areas.
Total Surface Area = 2 x (Area of Top) + 2 x (Area of Side) + 2 x (Area of Front)
Total Surface Area = 2(108) + 2(54) + 2(72) = 216 + 108 + 144 = 468 square units
Therefore, the total surface area of the rectangular prism is 468 square units.
