The Great Pyramid of Cheops is a square-based pyramid. The base has sides of 230m, and the height is 147m.

Using the same material, what would the height be if you gave the base sides of 240m?

Answer to nearest meter and explained solution please.

height = 140.875m

Step-by-step explanation:

Volume of first pyramid= base * height /3 = 230*147/3= 11270

if the base is 240, volume is remain -> height = volume *3 /base

                                                                            = 11270*3/240 =140.875m

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

if x = 1, then the answer is 3.5
