Question

You have a square piece of bread that is 5 inches long and 5 inches wide. It it h inches high. The crust of the bread if 50% of the total surface area of the bread. What is the height, h, of the bread?

Answer 1

2.5 inches

Explanation:

equation :

(4×5) × h = 50% × [(2×5×5)+(4×5)×h]

20×h = 0.5 × (50 +20h)

20h = 25+10h

20h-10h= 25

10h = 25

h = 25/10

= 2.5 inches
