Build a cement road with a width of 3.6 meters and a thickness of 20 cm. If 7.2 cubic meters of concrete is mixed, how many meters can it be paved?

Build a cement road with a width of 3.6 meters and a thickness of 20 cm. If 7.2 cubic meters of concrete is mixed, how many meters can it be paved?


20 cm = 0.2 m, 7.2 △ 3.6 × 0.2, = 7.2 △ 0.72, = 10 m; a: it can be paved for 10 m



Build a 3.5m wide and 30cm thick cement road. If 63 cubic meters of concrete are mixed, how many meters of road can be paved


63 / 3.5 / 0.3 = 60m, which can be repaired 60m theoretically



A road repair team uses 3200 cubic meters of stones to pave a section of road 2000 meters long and 8 meters wide. How thick can it be?


2000 * 8 = 16000 square meters
3200 divided by 16000 = 0.2m
