Based on the percentage of total daily calories in the number of calories needed how many biscuits and packages of pemmican and packages of butter and cocoa just one person need each day

Here for a good time of free question aha

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
