Question

A rectangular solid measures 1.089 hm by 3.78 dam by 50dm. express your volume in inches. (2.54 cm = 1 inch)

Answer 1

First of all we need to convert all the units into inch

Given the length of rectangular solid,

l = 1.089 hm = 1.089 hm x (10000 cm / 1 hm) x (1 inch / 2.54 cm) = 4287.4 inch

breadth of the rectangular solid,

b = 3.78 dam x (1000 cm / 1 dam) x (1 inch / 2.54 cm) = 1488.2 inch

height of the rectangular solid

h = 50 dm = 50 dm x (10 cm / 1 dm) x (1 inch / 2.54 cm) = 196.85 inch

Hence volume of the rectangular solid, V = lxbxh

= 4287.4 inch x 1488.2 inch x 196.85 inch = 1256003134 inch³ (answer)
