Volume of the square pyramid = 64 in³
Surface area of square pyramid = 144 in²
B = 64 in²
P = 32 in
h = 3 in
l = 5 in
Step-by-step explanation:
The base is a square.
Volume of a square pyramid = area of base × height/3
h = height = 3 in
Area of base = side length²
side length = 8 in
Area of base = 8² = 64
Volume of the square pyramid = 64 × 3/3 = 192/3
Volume of square pyramid = 64 in³
B = area of base
B = 64 in²
P = perimeter of base
perimeter of base = 4(length) = 4(8)
perimeter of base = 32 in
P = 32 in
Surface area of square pyramid = Area of base + 1/2 × perimter of base × slant height
l = slant height = 5 in
l = 5 in
Surface area of square pyramid = 64 + 1/2(32)(5)
Surface area of square pyramid = 64 + 80
Surface area of square pyramid = 144 in²
