Question

a block measures 3.5 cm long 2.8 cm wide and 1.6 cm deep. the density of the block 2.5 g/cm. calculate the volume of the block.

Answer 1

The volume is

(length) x (width) x (height)

= (3.5 cm) x (2.8 cm) x (1.6 cm)

= 15.68 cubic cm.

Notice that you don't need the density to calculate the volume.

Answer 2

Volume of a block can be found by: length × width × height. So:

3.5cm × 2.8cm × 1.6cm = 15.68cm^3
