Priya's rectangular prism measures inches by inches by 2 inch.
dedylja [7]

The number of cubes with edge length ⅕ inch that will fit in the prism is: 1,920 cubes

<h3>Volume of a Rectangular Prism</h3>

Volume of a rectangular prism = length × width × height

<h3>Volume of a Cube</h3>

A cube has equal edge length. Therefore, the volume of a cube = a³, where a is the edge length.

Given the following,

Dimensions of Priya's Rectangular Prism:

2⅖ = 2.4 inches

3⅕ = 3.2 inches

2 inches

Volume of the Rectangular Prism = 2.4 × 3.2 × 2 = 15.36 in.³

Dimension of the cubes:

edge length = ⅕ inch

Volume of the cube = (⅕)³ = 0.008 in.³

The number of ⅕ inch edge cube that will fit in the prism = Volume of Prism / Volume of Cube

= 15.36/0.008 = <em>1,920 cubes </em>

Factor the expression 30a+35​
kherson [118]
<h3>Answer is   5(6a+7)</h3>

=====================================

The GCF is 5, which can be factored out of the expression

Note how

30a = 5*6a

35 = 5*7

So we see the common factor between the two terms. You use the distribution property to pull out that 5. If you were do distribute the 5 back in, you'd get

5(6a+7) = 5*6a+5*7 = 30a+35
