bill is replacing the grass in his yard with cement .the yard is 300m long and 100m wide. if cement is 15cents per cm how much would it cost?

Answer 1

He's replacing the grass with concrete, not cement.

300 m = 3,000 cm
100 m = 1,000 cm

3,000 * 1,000 = 3,000,000 square cm

3,000,000 * 0.15 = $__________

Answer 2

3000000*0.15= $450000
