+130511 A cuboid has a length of 6cm, a with of 1.5cm, and a depth of 1.5cm . Work out the total surface area
--------------------------------------------------------------------------------------------------------------------------
The surface area is
4(6 x 1.5) + 2(1.5 x 1.5) = 4(9) + 2(2.25) = 36 + 4.5 = 40.5cm2
