Question

What is the surface area of this rectangular prism?

Answer 1

396 in²

Explanation:

The area of a rectangular prism is given by the formula:

`A = 2(wl+hl+hw)`

A = 2((6×7)+(12×7)+(12×6))

A = 2(42+84+72)

A = 2(198)

A = 396

Units will be in² since it is area. It will not be in³ as it is not volume!
