Question

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?

Answer 1

2.52kg

Step-by-step 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

Answer 2

2.52kg

Step-by-step 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
