Question

a box made of sheet metal coats ruppes 2820 at the rate of $30 per square meter if the box is 5 meter long and 4 meter wide find its height​

Answer 1

Step-by-step explanation:

surface area of box = 2820/30 = 94 sq m

surface area = 2(lb + lh + bh) = 94

(20 + 5h + 4h) = 94/2= 47

9h = 47 - 20 = 27

h = 27/9 = 3 m
