Question

find the total surface area of cuboid whose dimensions are lenth = 15 cm,breath = 15 cm,hieght = 5 cm​

Answer 1

Explanation:

ANSWER

Volume of a cuboid of length l, breadth b and height h =l×b×h

So, the volume of the cuboid with length =15cm, breadth =15cm and height =5cm =15×15×5=1125cm^3

Total surface area of a cuboid of length l, breadth b and height h =2(l×b+b×h+l×h)

So, the total surface area of the cuboid with length =15cm, breadth =15cm and height =5cm =2(15×15+15×5+15×5)=2(225+75+75)=750cm^2
