Answer:

The answer is 42.67 cubic inches.

Step-by-step explanation:

Both the models are in the shape of a square pyramid.

The length of the sides of the base for both the models is 8 inches.

Amy’s model is 5 inches tall and Alex’s model is 3 inches tall.

The volume is given by :

a^{2}\frac{h}{3}

So, Amy's figure volume is :

8^{2}\times \frac{5}{3} = 106.67 cubic inches

And Alex's figure volume is:

8^{2}\times \frac{3}{3} = 64 cubic inches

So, the difference between volumes is = 106.66-64=42.67 cubic inches.

The answer is 42.67 cubic inches.

Answer:2/11

Step-by-step explanation:

A fraction is in simplest form when the top and bottom cannot be any smaller

Firstly start by getting the common factors between 1 and 4 in 1/4 and 11 and 8 in 11/8. The common factor is 1 in 1/4 and 1 in 11/8. 1÷1/4÷1= 1/4. 11÷1/8÷1 = 11/8.

1/4÷ 11/8 =2/11.
