A rectangular box of length 40cm, breadth 25cm and height 20cm is to be made of tin. What is the area of tin sheet required?

Answer 1

the answer of this question is 4600

Answer 2

L= 40 cm
B= 25 cm
H= 20 cm
We have to find area of tin sheet required.
So Clearly Whole surface area of a cuboid is given by
2(lb+bh+hl)
2(40.25+25.20+20.40)
2(2300)
4600

Thus, 4600 CM square of tin sheet is required
