Answer For Number 6 is $30

Step-by-step explanation:

We can find how much molly would save by first finding out how much 20% of $275 is. We can do that by multiplying 275 by 0.20 since 0.20 is 20% in decimal form

[tex]275*0.20 = 55[/tex]

Now that we know 20% of 275, we can find the price of the microwave at store B by subtracting 55 from the original price.

[tex]275 - 55=220[/tex]

Now we can find how much Molly would save by subtracting our discounted price from the price of the microwave from store A

[tex]250-220=30[/tex]

Hence, the amount she would save is $30

First consider the volume of the given figure
Volume =length x width x height
V=L x W x H
B=2 1/2=2.5 cm , L=2 cm , H=1 cm
V= 2.5 x 2 x 1 =5 cm3

Considering the volume of the given cube
L=H=W
For a cube the sides are the same
V = L x W x H L = 1/2 = 0.5
V= (L)3
V=(0.5)3
V=0.125 cm3

Hence number of cubes
= volume of cube / volume of fig
= 0.125/5

Answers

The volume of the prism that is completely filled with 72 cubes that have edge lengths of 1/2 in. is 9 in³.

What is a prism?

A prism is a 3-dimensional shape, with two identical shapes facing each other.

To calculate the volume of the prism, we use the formula below.

Formula:

The volume of the prism (V) = 72×volume of one cubeV = 72L³............. Equation 1

Where:

V = Volume of the prismL = Length of the cube

From the question,

Given:

L = 1/2 in

Substitute these values into equation 1

V = 72(1/2)³V = 72(1/8)V = 9 in³

Hence, the volume of the prism is 9 in³.
