and a height of 6 cm.
What is the surface area of Hannah's rectangular prism?

Answer 1

Answer:

Area =136cm²

Area =2(wl+hl+hw)=2·(2·7+6·7+6·2)=136cm²

Answer 2

The required surface area of the rectangular prism is 396 cm².

Given that,
Hannah has a rectangular prism with a length of 7 cm, a width of 2 cm, and a height of 6 cm.
