Come help a sister out on 2 geometry questions please

PSYCHO15rus [73]

1- question

Data:
width = 6 cm
length = 5 cm
height = 8 cm

<span>First we will find the area of the base that is square, we have:
</span>
Ab = 6 * 5
Ab = 30 cm²

<span>Now we will calculate the volume of a square pyramid, we have:
</span>Formula: $V = \frac{1}{3} A_{b} *h$

Solving:
$V = \frac{1}{3} A_{b} *h$
$V = \frac{1}{3}*30*8$
$V = \frac{240}{3}$
$\boxed{\boxed{V = 80\:cm^3}}\end{array}}\qquad\quad\checkmark$

Answer:
D) 80 cm³

2- question:

Data:
width = 7 in
length = 7 in
height = 9 in

First we will find the area of the base that is square, we have:

Ab = 7 * 7
Ab = 49 in²

Now we will calculate the volume of a square pyramid, we have:
Formula: $V = \frac{1}{3} A_{b} *h$

Solving:
$V = \frac{1}{3} A_{b} *h$
$V = \frac{1}{3}*49*9$
$V = \frac{441}{3}$
$\boxed{\boxed{V = 147\:in^3}}\end{array}}\qquad\quad\checkmark$

Answer:
C) 147 in³

BC has one endpoint

irina1246 [14]

Answer:

Step-by-step explanation:

(3 + x)/2 = 6

3 + x = 12

x = 9

(2 + y)/2 = -2

What it the nearest intger to cube root 25

yulyashka [42]

Since we know the cube of 2 is 8 and the cube of 3 is 27, we know it must be between these two numbers, and since 25 is much closer to 27 than it is to 8, we can say the closest integer is 3.
