Haley simplifies 3^5 · 4^5 and gets the result 12^10, but lacey is not sure. is haley correct?

what happened is Haley didn't get enough syrup in her pancakes.

Given:
height = 1.8
length = 2.4
width = 1.2

The solid figure that the stairs can be broken into is RECTANGULAR PRISM.
Its dimension would be 2.4 by 1.2 by 1.8

We need to get the volume of 1 solid rectangular prism.
Volume = length * width * height
V = 2.4 * 1.2 * 1.8
V = 5.184 cubic units

Let us assume that the unit measure used is feet.
It is said that the weight of concrete is approximately 150 pounds per cubic foot.
To get the total weight of the concrete, multiply volume by 150 pounds per cubic foot.

5.184 cubic feet * 150 pounds/cubic ft = 5.184  * 150 pounds = 777.60 pounds
