Answer:
You find the area of all the faces of the square pyramid, then add them together to get the surface area.
25 ÷ (6 - 1) = 25 ÷ 5 = 5, she saved 5 nickels,
5 nickels = 5 × 5 = 25 cents = $0.25
5 + 25 = 30, she saved 30 dimes, 30 dimes = 300 cents = 3 dollars.
3 + 0.25 = $3.25, she saved $3.25 in all.
Half-perimeter=length+width=width+3+width=43, 2×width=40 so width=20cm and length=23cm.
