Question

Water flows from manjeets shower at a rate of 12 litres per minute. the water from the shower flows into a tank that is a cuboid of length 90 cm and width 75 cm
calculate the increase in the level of water in the tank when the shower is used for 7 minutes

Answer 1

Answer:

90×75=6750cm²

time take=12 litres/minutes

90×75×12=81000

Answer 2

Answer:

Step-by-step explanation:

Find the area of the cuboid--> 90 x 75 = 6,750 cm^2

Multiply that by 1 cm to get volume with height at 2 cm --> 6750 x 1 = 6,750cm^3

Calculate how many liters flow in 12 minutes --> 7 x12 = 84 liters

84 liters = 84,000 cm^3

divide 84,000 by 6750 = 12.4444  

height = 12.44 cm
