Question :-

rectangular box of dimensions 40 cm x 25 cm and 20 cm is to be made of tin find the area of the tin sheet needed if the box has a lid also.​

Answer 1

$\huge\underline\mathfrak\purple{Answer:-}$

The tin sheet required if the box has a lid also is 37000 sq.cm

$\underline\red{Step-by-step-explanation:}$

Length of box = 40 m = 400 cm

Breadth of box = 25 cm

Height of box = 20 cm

Total surface area of cuboid box = 2(lb+bh+hl)2(lb+bh+hl)

→ 2(400×25+25×20+20×400)

→37000cm

Hence, The tin sheet required if the box has a lid also is 37000 sq.cm.
