Question

A steel girder is 12 m long; 75 cm broad and 30 cm thick. What is its cost at 8.500 per m cube ​

Answer 1

Answer:

cost of 1 m cube is 8.5

total volume of girder is 12×.75×.3 = 2.7m cube

so total cost is 2.7×8.5 =22.95

Answer 2

Answer:

RS. 22.95

Step-by-step explanation:

volume =  Length × Width × Height

length = 12 m

width = 75cm = 0.75 m

height = 30 cm = 0.3 m

v= 12 x 0.75 x 0.3

volume = 2.7cubic m

1 cubic meter = 8.500 rs

2.7 cubic meter = 2.7 x 8.500 = 22.95 rs
