Question

Aubrey has a new art box in the shape of a rectangular prism. The box is 5  inches, by 8 inches, by 2  inches. The only thing in the art box is a new pink eraser with the dimensions shown below.


the erase is 0.25, 1 and 2inches

What is the volume of the art box not taken up by the eraser?

Answer 1

To solve this problem you must apply the proccedure shown below:
 The total volume of the art box not taken up by the eraser is:
 Vt=V(artbox)-V(eraser)

 V(eraser)=0.25 inchesx1 inchx2 inches
 V(eraser)=0.5 inches³

 V(artbox)=5 inchesx8 inchesx2 inches
 V(artbox)=80 inches³

 Vt=80 inches³-0.5 inches³
 Vt=79.5 inches³

 The answer is: 79.5 inches³

Answer 2

Answer:

The answer is 1196 cm^3

Step-by-step explanation:

First let's find the volume of the art box.

V  = lwh

V  = 20 * 12 * 5

V  = 1200

​Now let's find the volume taken up by the eraser.  

V  = lwh

V  = 4 * 2 * 0.5

V  = 4

​We can subtract to find the volume of the box that is not taken up by the eraser.

1200 - 4 = 1196cm^3
