Norm must pay to have trash collected he can put out 1 barrel of trash per week a rectangler container measure 32 inches by 18 i

Ainat [17]

Answer:

The Cycling Rick container can hold more trash.

Step-by-step explanation:

The rectangular container is basically a rectangular prism, so to find its volume, we are using the formula for the volume of a rectangular prism:

$V=whl$

where

$V$ is the volume

$w$ is the width

$h$ is the height

$l$ is the length

We know that the rectangular container is 32 inches by 18 inches by 10 inches, so $l=32in$ , $w=18in$ , and $h=10in$ . Let's replace the values in our formula:

$V=whl$

$V=(18in)(10in)(32in)$

$V=5760in^3$

The rectangular container can hold 5760 cubic inches of trash.

Now, the Cycling Rick container is basically a cylinder, so to find its volume, we are suing the formula for the volume of a cylinder:

$V=\pi r^2h$

where

$V$ is the volume

$r$ is the radius

$h$ is the height

We know that the its height is 30 inches, so $h=30in$ . Since the container is 20 inches wide, its diameter is 20 inches, and since the radius is half the diameter, $r=\frac{20in}{2} =10in$ . Let's replace the values:
