Determine the amount of stone needed to build one of the pyramids with a height of 145 m and a square base with a side length of 230m? Find the volume.

Step-by-step explanation:

We would apply the formula for determining the volume of a square based pyramid which is expressed as

Volume = 1/3 × base area × height

From the information given,

Side length = 230m

Height = 145m

Since the base is a square,

Base area = 230² = 52900

Therefore,

Volume = 1/3 × 52900 × 145

Volume = 2556833.3 cubic meters

The amount of stone needed is expressed in volume.

i just took the test, the correct answer is .. 31.5 in.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
