Question

The dimensions of a tin box are 4m * 3.5 m * 3m. If 25 such boxes are to be made. Find the area of the tin sheet required.

​

Answer 1

1750 m²

Explanation:

Dimension of tin box = 4m * 3.5 m * 3m

Length, l = 4 ; width, W = 3.5 ; height, h = 3

Total Surface area= 2(lw * lh * wh)

= 2((4*3.5) + (3.5*3) + (3.5 * 3))

= 70 m³

Area required to make 25 ;

25 * 70m³

= 1750 m³
