Question

a pit 8m long,5mbroad and 1.5 deep is dug in the ground.The soil so dug is evenly spread over a rectangular plot 25m long and 16m broad.Find the thickness of the layer of the soil spread over the rectangular plot

Answer 1

Answer:

Lenght =8m (800cm)

Breadht =5m (500cm)

Height =1.5m (150cm)

Volume =l*b*h

V = 800*500*150

=60000000 cu cm

Area of the rectangular field =l*b

Lenght=25m(2500cm)

Breadht =16m(1600cm)

Height = V/l*b

60000000/4000000

15cm

0.15m
