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? Volume of cement (to the nearest cubic foot) = cubic feet.

Answer 1

Answer: 300 cubic feet cement

Explanation:

Given: The pilings are in the shape of rectangular solids,the height of the piling = 10ft.

The length of the piling = 3 ft. square

Now, since we are going to pour cement into 10 of these forms.

Thus, the amount of the cement we will pour is given by ;-

`\text{Volume}=3*10*10=300\text{cubic feet}`

Hence, we will pour 300 cubic feet cement.

Answer 2

Volume V=3*10=30 feet³ -- > one piling

10 pilings----------------- > V=30*10=300 feet³

The answer is 300 feet³ of cement
