Question

What is the surface area in square feet of a rectangular prism with dimensions of 2 feet by 3 feet by 4 feet as shown in the net?

Answer 1

Answer: 52 square feet

Step-by-step explanation:

The surface area of a rectangular prism is given by :-

$S.A.=2(lw+wh+hl)$, where l is length , w is width and h is height of then prism.

Given: Dimensions of the rectangular prism :   $l\times w\times h=$ 2 feet by 3 feet by 4 feet

Then , the surface area of a rectangular prism will be:-

$S.A.=2(2(3)+(3)(4)+(2)(4))\\\\\Rightarrow\ S.A.=52\text{ inches}^2$

Hence, the surface area  of a rectangular prism= 52 square feet
