The surface area of the cuboid with the given length, width and height is 1,160 square cm.
What is the surface area of the cuboid?
Length = 20 cm
Width = 8 cm
Height = 15 cm
Surface area of a cuboid = 2(lh + wh + lw)
= 2(20×15 + 8×15 + 20×8)
= 2(300 + 120 + 160)
= 2(580)
= 1,160 square cm
Therefore, 1,160 square cm is the surface area of the cuboid.
