lorasvet [3.4K]

Hello Human!

The answer to this is:

a = 40 feet

<h2><u>EXPLANATION:</u></h2><h2><u></u></h2>

<u></u>

Given:

V = 19,200 feet³  volume of the sculpture

H = 36 feet  height of the sculpture

a = ?  side length of the square base

The formula for calculating the volume of a pyramid is:

V = B H / 3  ⇒ B = 3 V / H

B = 3 · 19,200 / 36 = 19,200 / 12 = 1,600

B = a²

a² = 1,600  ⇒  a = √1,600 = 40 feet

a = 40 feet

Hope It Helped!

13. t plus the product of three and t​
Sindrei [870]

Answer:

4t

Step-by-step explanation:

Let's form an equation here just to put it visually.

So it would be t+3*t

We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)

Now we can do t+3t which is 4t

If this doesn't make sense, then you can look at it this way

You do 1t+3t and since they're like terms, you can combine them and do 4t.
