Answer:
cost : 7750 rupees
Step-by-step explanation:
length - 25m
breadth -15m
height -5m
total surface area= lateral surface area + area of the floor
lateral surface area =2h(l+b)
area of the floor =lb
=2h(l+b) +lb
=2×5(25+15)+25×15
=10(40)+375
=400+375
=775
Cost of cementing the floor and the walls = 10 × 775
=7750 rupees
