Find the volumes of the figures below. i don't need work just answers

Hello!

To find the volume of a square pyramid, use the formula: V = 1/3b²h.

In this formula, b is a side length of the base, and h is height of the figure.

Figure 1

Since we are given the side length of the base, which is 18 inches, and the height, which is 12 inches, we can find the volume.

V = 1/3(18)²(12)

V = 1/3(324)(12)

V = 108(12)

V = 1296 inches³.

The volume of the first figure is 1296 inches cubed.

Figure 2

Since we are not given the height of this figure, we need to find it using the pythagorean theorem. In this case, we need to find a and b. Since the base of this triangle is a square, to find b, it is half the side length of the base.

22 inches / 2 = 11 inches

With the value of b, we can find the height, or a.

a² + 11² = 24²

a² + 121 = 567 (subtract 121 from both sides)

a² = 455 (take the square root of both sides)

a = √455

With the height being √455, we can find the volume.

V = 1/3(22)²(√455)

V = 1/3(484)(√455)

V = (484/3)(√455)

V = 3441.3576..

This can be rounded to 3441.36 inches cubed.

Therefore, the volume of figure two is 3441.36 inches cubed.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
