Answer:
Step-by-step explanation:
Data:
s = 5 in
l = 9 in
1. Lateral surface area
The general formula for the lateral surface area L of a regular pyramid is
L =½pl
where p represents the perimeter of the base and l the slant height.
The base is a square, so
p = 4 × 5 = 20 in
L = ½pl = ½ × 20 × 9 =
2. Total surface area
Total surface area = lateral surface area + area of base
S = L + B
B = b² = 5² = 25 in²
S = 90 + 25 =
54
224 cubes
The volume of the cubes is 1/64. Because 1/4*1/4*1/4=1/64.
The volume of the prims is 14/4 because 7/4*2*1=14/4.
Take the 14/4 and divide it by 1/64.
Which equals 896/4 = 224
