Find the volume of this square<br> based pyramid.<br> 5ft<br> 6 ft<br> [? ]ft
Sav [38]

Answer:

48 ft³

Step-by-step explanation:

To find the height, you can use the slant height and the base.

Using the Pythagorean Theorem and 3 as the triangle's base,

a²+b²=c²

3²+b²=5²

9+b²=25

b²=16

b=4

The height of the pyramid is 4.

Volume formula for the pyramid is \frac{1}{3} *b*h

Inserting our measurements:

\frac{1}{3} *6*6*4=\\2*6*4=\\12*4=\\48

3a-13=47 a= pls help ive been stuck on this for an hower
patriot [66]

Hey there!

Explanation:

First, you had to do is add by 13 from both sides of an equation.

3a-13+13=47+13

Then, simplify or add by the numbers.

47+13=60

3a=60

Next, you can also divide by 3 from both sides of an equation.

\frac{3a}{3}=\frac{60}{3}

And finally, simplify and divide by the numbers,

60/3=20

*The answer must have a positive sign.*

\boxed{a=20}

Hope this helps!
