General Maths Puzzle Numerical Ability Time Distance and Speed

A hall is 15 c.m long and 12 c.m broad.If the sum of the areas of floor and ceiling is equal to the sum of the areas of four walls.Then the volume of the halls is?

Read Solution (Total 1)

1200 cm^3

If height of the hall=x, given length=15, breadth=12
Area of floor+Area of ceiling=15*12+ 15*12=360
Areas of the four walls=(2*12*x)+(2*15*x)=54x
As 54x=360, x=20/3
Volume of the hall=Length*Breadth*Height=15*12*20/3=1200
