Question

Help pleas for 12 points

Answer 1

given:

height= 3 ft

width= 3 ft

length= 9 ft

to find:

the surface area of the given prism.

solution:

`s.a = 2(hw + wl + hl )`

`s.a = 2(3 * 9 + 3 * 9 + 3 * 3)`

`s.a = 126 \: {ft}^(2)`

therefore, the surface area of the given prism is 126 square feets.

Answer 2

126 ft²

Explanation:

surface area of rectangular prism: 2(LW + HW + WL)

Here Given:

• Length: 9 ft

• Width: 3 ft

• Height:3 ft

Surface Area:

• 2(LW + HW + WL)

• 2(9*3 +3*3 + 9*3)

• 2(27 +9 + 27)

• 2(63)

• 126
