Answer 1

Hello!!! :)))

A=2(wl+hl+hw)=2·(3·6+7·6+7·3)=162

Answer: 162 cm2

Hint when finding the surface area it will be
`cm^(2)`,
`in^(2)` ,
`ft^(2)` , etc.

Answer 2

126cm³

Explanation:

In order to find the volume of the cube, you must multiply all three units together. So we would multiply 7·6·3=42·3=126. Then since we multiplied 3 units together, our final answer is 126cm³
