a. f the following tanks? Give your answer in litres. (1 € = 1000 cm) 40 cm 16 cm 20 cm 21 cm 64 cm 57 cm 17 cm 17 cm
b. 64 cm 17cm 17cm 57cm
a.
16 cm × 21 cm × 20 cm
= 6 720 cm³
40 cm × 21 cm × 20 cm
= 16 800 cm³
16 800 cm³ - 6 720 cm³
= 10 080 cm³
10 080 cm³ = 10.08 litres
b.
64 cm × 17 cm × 17 cm

57 cm × 17 cm × 17 cm
= 16 473 cm³
18 496 cm³ - 16 473 cm³
= 2 023 cm³
2 023 cm³ = 2.023 litres
