Example 1: What is the surface area of a cuboid with length, width and height equal to 4.4 cm, 2.3 cm and 5 cm, respectively? Solution: Given, the dimensions of cuboid are: length, l = 4.4 cm width, w = 2.3 cm height, h = 5 cm Surface area of cuboid = 2(wl+hl+hw) = 2·(2.3·4.4+5·4.4+5·2.3) = 87.24 square cm. Example 2: What is the volume of a cylind...
