Answer:
100 oranges are in the stack
Step-by-step explanation:
A grocer stacks orange in a pyramid-like stack whose rectangular base is 5 oranges by 8 oranges. Each orange above the first level rests in a pocket formed by four a oranges in the level below. The stack is completed by a single row of oranges
First Row = 5 * 8
Second Row = 4 * 7
Third Row = 3 * 6
Fourth Row = 2 * 5
Fifth Row = 1 * 4
Total oranges = 40 + 28 + 18 + 10 + 4
= 100
100 oranges are in the stack
