7. The largest of the Great Pyramids in Egypt was built with a square base, having edges that measured 754 feet and a height of 481 feet. Today, after
years of erosion, the base edges are 745 feet and its height is 471 feet. To the
nearest cubic foot, find the difference between the original and current
volumes of the pyramids.
Please show work

Difference between the original and current volumes = 4013140.30 cubic feet

Step-by-step explanation:

Largest pyramid has the square base with one edge = 754 feet

Area of the square base = (Side)²

                            = (754)²

                            = 568516 square feet

Volume of the pyramid =

                                       =

                                       = 91152065.3 cubic feet

After erosion,

Area of the base = (745)² = 555025 square feet

Volume of the pyramid =

                                       = 87138925 cubic feet

Difference between the original and current volumes of the pyramid

= 91152065.30 - 87138925

= 4013140.30 cubic feet

okay, i have to be honest, this equation is a little tricky because the use of "h" is kind of weird, using it twice to show...what exactly i am not too sure.

the

The variable "t" is the amount of taxes she has to pay for repairing her cracked phone. "t" is shown as an extra amount of money to pay, and since it does not state that taxes were dependent on the amount of time it took to repair the phone, it must have been a fixed price. The amount of money it takes to repair the phone (tax not included) is shown to be dependent on time, though.
