Well, the volume of a pyramid is 1/3 b * h
What is the height of one of these pyramids? Well, they tell you that it's 10. What is the base? It's 6 * 8 = 48
10 * 48 * 1/3 = 160
Now multiply by 2 because there are two pyramids. One on top and one one bottom. 160 * 2 = 320

Well if the alloy makes the 1000 grams, but you are dealing with copper that isn't even 100% copper, than you either need 55% more copper, which isn't given, which means you really need 550 grams of alloy copper.
A= 1.142 m/hr
Width of beach at 8 p.m. = 36 m
Width of beach at 3 a.m. = (36-8) m =28 m
Average change in width(A) = change in width (Width of beach at 8 p.m.-Width of beach at 3 a.m.0/ time in hours
A= ( 36-28)/ 7
A= 8/7 m/hr
A = 1.142 m /hr
