Question

The length and breadth of a cuboid are 15cm , 10cm respectively and Volume of

cuboid is 750cm3

,find it’s height ?​

Answer 1

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 =10cm and height =8cm=15×10×8=1200cm

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 =10cm and height =8cm=2(15×10+10×8+15×8)=2(150+80+120)=700cm
