Ihave a question for you guys. george is buying gravel to put on his driveway, the driveway is shown below. he needs the gravel to be 2 cm deep. he can buy gravel in bags that weigh 1 tonne, and cover 1,000,000 cm cubed. how many bags will he need to buy. top is 12.2m and side is 3.0m show your working out .

If George's driveway is a rectangle 12.2 m by 3.0 m, its dimensions in cm are

... 1220 cm long × 300 cm wide × 2 cm deep

Thus the volume of gravel required is

... (1220 × 300 × 2) cm³ = 732,000 cm³

George needs about 0.732 bags, so he will probably need to buy 1 bag.
