A square pyramid has a height of 6 units and a volume of 70 units3. If a square prism has the same base area and volume as the s

inysia [295]

Answer:

The height is 2 units

Step-by-step explanation:

Find the area of the base of the square pyramid

we know that

The volume of the square pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base and H is the height of the pyramid

we have

$H=6\ units$

$V=70\ units^{3}$

substitute in the formula and solve for B

$70=\frac{1}{3}B(6)$

$B=70/2=35\ units^{2}$

step 2

Find the height of the square prism

we know that

The volume of the square prism is equal to

$V=Bh$

where

B is the area of the base and h is the height of the prism

we have

$B=35\ units^{2}$

$V=70\ units^{3}$

substitute in the formula and solve for h

$70=(35)h$

$h=2\ units$

Damm [24]

4 feet 8 inches
______________________________________________________________

First find how many inches are in 4 feet + 8 inches. There are 12 inches in 1 foot. Multiply 4 x 12 = 48. Add 8 to 48 = 56. Laney's height in inches is 56 inches.
______________________________________________________________

There are 2.54 centimeters in 1 inch. Multiply 56 x 2.54 = 142.24.
______________________________________________________________

Laney's height is 142.24 centimeters.

iris [78.8K]

Answer:

95°

Step-by-step explanation:

<u>Straight angle is 180°</u>

JKL = MKL + JKM
180° = 85° + x
x = 180° - 85°
x = 95°
