Excavation for the base of the cottage has dimensions 4.5 m x 3.24 m x 60 cm. The excavated soil will increase its volume by one-quarter. Calculate the volume of excavated soil.

Correct answer:

V =  10.935 m3

Step-by-step explanation:

a=4.5 m b=3.24 m c=60/100=53=0.6 m V1=a b c=4.5 3.24 0.6=2502187=8.748 m3 V=(1+1/4) V1=(1+1/4) 8.748=2002187 m3=10.935 m3
