8 times as much

How many times as much means 9 times what will give us 72.

72 / 9 = 8

Little bro’s $9 x 8 = Audrey’s $72

steposvetlana [31]

The number of basketball that will fill up the entire office is <u>approximately 16,615.</u>

<em><u>Recall:</u></em>

Volume of a spherical shape = $\frac{4}{3} \pi r^3$

Volume of a rectangular prism = $l \times w \times h$

<em><u>Given:</u></em>

Diameter of basketball = 9.5 in.

Radius of the ball = 1/2 of 9.5 = 4.75 in.

Radius of the ball in ft = 0.4 ft (12 inches = 1 ft)

Dimension of the office (rectangular prism) = 20 ft by 18 ft by 12 ft

First, find the volume of the basketball:

Volume of ball = $\frac{4}{3} \pi r^3 = \frac{4}{3} \times \pi \times 4.75^3\\$

Volume of basketball = $448.92 $ in^3$

Convert to $ft^3$

$1728 $ in.^3 = 1 $ ft^3$

<em>Therefore,</em>

Volume of basketball = $\frac{448.92}{1728} = 0.26 $ ft^3$

Find the volume of the office (rectangular prism):

Volume of the office = $20 \times 18 \times 12 = 4,320 $ ft^3$

Number of basket ball that will fill the office = Volume of office / volume of basketball

<em>Thus:</em>

Number of basket ball that will fill the office = $\frac{4,320}{0.26} = 16,615$

Therefore, it will take approximately <u>16,615 balls</u><u> to fill up the entire office</u>.

I am hoping that the a in c = ad is supposed to be x.

The formula for circumference is c = pi * diameter with 3.14 substituting for pi.

Let’s plug in some values

172.7 = 3.14d

Divide

55 = d

The diameter should be 55 cm.

the volume of a rectangular pyramid is 125 cm cubic inchs. what is the volume of a rectangular prism having a congruent base and

Mnenie [13.5K]

I am confused with regards to the unit. You wrote cm cubic inches. So, I'll just use cubic unit.

Given:
Volume of rectangular pyramid is 125 cubic unit

Volume of rectangular pyramid = (length * width * height) ÷ 3

Volume of rectangular prism = length * width * height

The main difference between the two volumes is the present of 3.

Volume of rectangular prism = Volume of rectangular pyramid * 3

V = 125 cubic unit * 3 = 375 cubic unit
