Question

how do you work out the surface area of a cubiod ?

Answer 1

Best Answer - Chosen by Voters

A1 = L XH X 2
A2 = B X H X2
A3 = L X B X 2

Total Area = A1+A2+A3

Answer 2

A cube has six surfaces. The opposite faces of a cuboid have the same size surface.

Top and Bottom surface individually = L X B
Left and right surface individually = L X H
Front and Back surface individually = B X H

Top and Bottom surface together = 2 X L X B
Left and right surface together = 2 X L X H
Front and Back surface together = 2 X B X H

Total surface = 2 x ( L x B + L x H + B x H )
