Examples on Surface Area of a Square Pyramid Formulas
Example 1: Calculate the total surface area of a square pyramid if its base is 10 cm and its slant height is 13 cm.
Solution:
We have,
a = 10
l = 13
Using the formula we have,
TSA = a2 + 2al
= (10 × 10) + (2 × 10 × 13)
= 100 + 260
= 360 sq. cm
Example 2: Calculate the total surface area of a square pyramid if its base is 6 cm and its slant height is 8.54 cm.
Solution:
We have,
a = 6
l = 8.54
Using the formula we have,
TSA = a2 + 2al
= (6 × 6) + (2 × 6 × 8.54)
= 36 + 102.53
= 138.53 sq. cm
Example 3: Calculate the total surface area of a square pyramid if its base is 11 cm and height is 9 cm.
Solution:
We have,
a = 11
h = 9
Using the formula we have,
TSA = a2 + 2a√(a2/4 + h2)
= (11 × 11) + (2 × 11 √(112/4 + 92))
= 121 + 232.05
= 353.05 sq. cm
Example 4: Calculate the total surface area of a square pyramid if its base is 14 cm and height is 10 cm.
Solution:
We have,
a = 14
h = 10
Using the formula we have,
TSA = a2 + 2a√(a2/4 + h2)
= (14 × 14) + (2 × 14 √(142/4 + 102))
= 196 + 341.8
= 537.8 sq. cm
Example 5: Calculate the lateral surface area of a square pyramid if its base is 3 cm and slant height is 4.27 cm.
Solution:
We have,
a = 3
l = 4.27
Using the formula we have,
LSA = 2al
= 2 × 13 × 4.27
= 25.63 sq. cm
Example 6: Calculate the lateral surface area of a square pyramid if its base is 13 cm and height is 10 cm.
Solution:
We have,
a = 13
h = 10
Using the formula we have,
LSA = 2a√(a2/4 + h2)
= 2 × 13 √(132/4 + 102)
= 310.1 sq. cm
Example 7: Calculate the lateral surface area of a square pyramid if its base is 9 cm and height is 14 cm.
Solution:
We have,
a = 9
h = 14
Using the formula we have,
LSA = 2a√(a2/4 + h2)
= 2 × 9 √(92/4 + 142)
= 264.7 sq. cm
