A container has the dimensions of 10cm x 80mm x 0.15m. The density of its contents is 2.1 g/cm3. What is the mass of the substance in kilograms?

2.52kg

Explanation:

80mm = 8 cm

0.15m = 15 cm

volume of the container = 10m × 8cm × 15cm

= 1200 cubic centimetres

mass = density × volume

= 2.1 × 1200

= 2520g

2520/ 1000

= 2.52kilograms

2.52kg

Explanation:

80mm = 8 cm

0.15m = 15 cm

volume of the container = 10m × 8cm × 15cm

= 1200 cubic centimetres

mass = density × volume

= 2.1 × 1200 = 2520g

2520/ 1000  = 2.52kilograms
