Find the height of a square pyramid that has a volume of 12 cubic feet and a base length of 3 ft

Mathematics

Tanzania [10]3 years ago
3 0
Now, a square pyramid is called that, because its base is a square.

if one side on its base has a length of 3, then all sides are 3 units long, since is a squarish base, and therefore the area of the base is 3x3 or 9 ft².

\bf \textit{volume of a pyramid}\\\\
V=\cfrac{1}{3}Bh\quad 
\begin{cases}
B=base's~area\\
h=height\\
--------\\
V=12\\
B=\stackrel{3\times 3}{9}
\end{cases}\implies 12=\cfrac{1}{3}9h\implies 12=3h
\\\\\\
\cfrac{12}{3}=h\implies 4=h

Answer:

Answer:

85t

Step-by-step explanation:

1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

hope this helps

What is the value of x in 5x - 7 = y, if y =8
quester [9]
<h3>Answer:  x = 3</h3>

To get that answer, we replace y with 8 and then isolate x.

5x-7 = y

5x-7 = 8

5x = 8+7

5x = 15

x = 15/5

x = 3
