a godown building is in a form where vertical cross-section paralell to the width side of the building is a rectangle 7m*3m, mounted by a semi-circle of radius 3.5m. the inner measurements of the cuboidal portion of the building are 10m*7m*3m. find the volume of the godown and the total interior surface area excluding the floor(base)
Given, radius of semi-circle = 3.5 m
Now, internal surface area (excluding the floor) = Surface area of four walls + Surface area of roof + Area of both cross-section
= 102 + 148.5
= 250. 5 m2
Similarly, volume of godown = volume of cuboidal portion + volume of vertical cross-section
Try finding the volume of godown yourself and if you face any difficulty then do get back to us.
