Question

What is the total surface area of rectangular prism?

Answer 1

So surface area is calculated by
2lw + 2lh + 2hw = SA
L is length
W is width
H is Height

SA is surface area.

So plug it in, (reminder this equation only works for cubes, rectangular prisms)

2(3)(6) + 2(3)(7) + 2(7)(6) = ?

So now follow order of operations to solve.
36 + 42 + 84 = 162

So 162m^2 is the surface area.

Answer 2

162 [m²].

Explanation:

required surface is:

A=(3*7+6*7+3*6)*2=162 [m²].
