Question

You have constructed wooden forms for pilings. the pilings are in the shape of rectangular solids, each measuring 10 ft. high and 3 ft. square. you are now going to pour cement into 10 of these forms. how much cement will you pour?

Answer 1

We first calculate for the volume of each of the figure by dividing all together the dimensions of the rectangular prism.
Volume = (10 ft)(3 ft)(3 ft) = 90 ft³
Then, multiply the volume of each prism by 10 to get the total amount of cement that needs to be poured.
Total volume = (90 ft³)(10) = 900 ft³
