A godown building is in the form as shown in the figure The vertical cross-section parallel to the width side of the building is a rectangle 7m x 3m mounted bvy a semi-circle of radius 3.5cm The inner measurements of the cuboidal portion of the building are 10 mx7mx3m. Find the volume of the godown and the total interior surface area excluding the floor (base) (Take `pi22/7`)

Text Solution

Verified by Experts

Total volume=volume of cube+volume of curve
`=7*3*10+385/2`
`=402.5m^m`
`A=(2pi*7)/(2*2)*10+(22/7*7/2*7/2*2)/2+2(7*3+10*3)`
`A=250.5 cm`.
