Question

the area of a base of a cubical water tank is 80 m square find the height of water is the tank is contain 2 × 10 to the power 5 litre water​

Answer 1

BY USING UNITARY METHOD

100 LITRES = 1M cube A

1 LITRE =(1/1000)

200000 LITRES = (1/1000)

200000 = 2000cu.m

$\pi {r}^{2} h = 200 {m}^{2}$
80h =200

h =200/80

h=2.5m
