Explanation

To find the smallest square slab size that can tile the floor without cutting, determine the greatest common divisor (GCD) of the floor's dimensions in centimeters: GCD of 1296 cm and 384 cm is 48 cm. Each slab measures 48 cm × 48 cm. The number of slabs required is (1296 ÷ 48) × (384 ÷ 48) = 27 × 8 = 216 slabs.
