Question

Jimmy's cedar trunk is in the shape of a rectangular prism and has a volume of 3/4 cubic yard. How many cubic blocks with a side length of 1/2 yard would Jimmy need to measure the volume of his trunk?

Answer 1

Answer:

6 blocks.

Step-by-step explanation:

Since, the volume of the rectangular prism = $\frac{3}{4}$ cubic yard,

Also, the side length of one block = $\frac{1}{2}$ yard,

Given, the shape of block is cubical,

We know that,

The volume of a cube is,

$V=(s)^3$

Where s is the side length of cube,

So, the volume of one block = $(\frac{1}{2})^3$

$=\frac{1}{8}\text{ cubic yards}$

Hence,

$\text{The number of blocks needs for finding the volume of trunk}=\frac{\text{Volume of trunk}}{\text{Volume of a block}}$

$=\frac{\frac{3}{4}}{\frac{1}{8}}$

$=\frac{3}{4}\times 8$

$=6$

Answer 2
