Question

. Six concrete posts are used to support a waterfront pier. Each post has dimensions 14 in x 14 in x 15 ft. The average density of the concrete is 2.4 g/cm3. ( 1g = 1 x 10-6 metric ton)

a. Calculate the volume of concrete (in m3) needed to make one post.

Answer 1

Answer:

0.58 m³

Explanation:

14 in (1 ft/12 in) = (14/12) ft

(14/12) ft×(14/12) ft×15 ft = 20.41 ft³ (1 m³/35.3 ft³) = 0.58 m³
