Given:
Length (l) = 22 cm
Width (w) = 12 cm
Height (h) = 7.5 cm
Lateral Surface Area (LSA) of a cuboid:
LSA = 2 × h × (l + w)
1. Calculate the sum of length and width:
l + w = 22 + 12 = 34 cm
2. Multiply by height and double it:
LSA = 2 × 7.5 × 34
LSA = 15 × 34 = 510 cm²
The lateral surface area of the cuboid is 510 cm².
