Question

5. How much sheet of metal is required to
make a cuboid?









​

Answer 1

Answer:

May be its 15

Step-by-step explanation:

Divide the volume of the cuboid with the volume of cube. The answer will be 15 pieces. so, you can 15 peices of cubes from that cuboid

Answer 2

Answer:

I think it is your answer☺️☺️☺️

Step-by-step explanation:

The tank is in the shape of a cuboid.

To find the area of the metal sheet required, we need to calculate the surface area of the cuboidal tank and subtract the area of the roof as it is an open tank.

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 =10m,

breadth =7.5m and height =3.8m=2(10×7.5+7.5×3.8+3.8×10)=2(75+28.5+38)=283m

2

Area of the roof =10×7.5=75m

2

Hence. area of the metal sheet required to make the open tank =283−75=208m
