A rectangular block of wood has dimensions 240 mm × 20 .5 cm × 0 .40 m . Calculate its volume in cm 3 .

Given, A rectangular block of wood has dimensions 240 mm × 20 .5 cm × 0 .40 m . Volume of block = length × width × height = 240 mm × 20 . 5 cm × 0 . 04 m Converting the units in cm = 2400 cm × 20 . 5 cm × 4 cm ∵ 10 mm = 1 cm ; 1 m = 100 cm Volume = 1968 cm 3 Hence, the calculate volume in 1968 cm 3 .
