lorasvet [3.4K]

64

Step-by-step explanation:

We will divide the volume of the larger cube with that if the smaller cube. However, we’ll first have to convert them to the same SI units;

12 inches  = 1 foot

Therefore the volume of the larger cube;

12 * 12 * 12 = 1728 inches cubed

The volume of the smaller cube;

3 * 3 * 3 = 27 inches cubed

Divide the two;

1728/27

= 64

A packing carton in the shape of a triangular right prism shown below. Find the volume of the prism.
Annette [7]

Answer: The volume is 120 in^3.

Step-by-step explanation:

-The volume formula for a triangular prism is:

(Height × Base × Length) /2

-So, you put the height, base, and length:

(4 × 6 × 10)

-Then, you solve:

(4 × 6 × 10)

(24 × 10)

240

-Divide 240 by 2:

240 ÷ 2

120

Therefore, the volume of a Triangular Prism is 120in^3.
