Question

a cube of side 45 cm is melted to form a cuboid of Size 15 cm × 12 cm × 10 CM approximately how many complete cuboids will be formed

Answer 1

Volume of cube=

${45}^{3}$

Volume of cuboid=

$15 \times 12 \times 10$

No.of cuboid=

$\frac{45 \times 45 \times 45}{15 \times 12 \times 10} \\ = \frac{2025}{40} = \frac{506.25}{10} = 50.625$

no.of cuboid =51approx.
