Answer:
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.
