Question

I would like some help for the mistake that Yul made and I would like to correct it as well

Answer 1

Given:

The length of a rectangular prism is 8 inches.

The breadth of a rectangular prism is 7 inches.

The height of a rectangular prism is 16 inches.

Yul fills the bird feeder to three-fourths of its capacity.

To find the amount of food that he filled:

Using the volume formula of cuboids,

`\begin{gathered} V=l* b* h \\ =8*7*16 \\ =896in^3 \end{gathered}`

So, the three fourth of the volume is,

`\begin{gathered} (3)/(4)V=(3)/(4)(896) \\ =3*224 \\ =672in^3 \end{gathered}`

But, he said that he used 896 square inches.

So, it is wrong.

The correct one is, he used 672 cubic inches of food to fill the bird feeder.
