Given: The surface area of a large cube is 2646cm2 and the smaller cube is 294cm2 Concept: Side of cube = √Surfacearea/6 Number of cube = Volume of the larger cube/Volume of the smaller cube Calculation: In a larger cube, the side is ⇒√2646/6 ⇒√441 ⇒21cm In a smaller cube, the side is ⇒√294/6 ⇒√49 ⇒7cm Now, The number of the smaller cube is formed from the larger cube is ⇒21×21×21/(7×7×7) ⇒3×3×3 ⇒27 ∴ 27
