Question

7. The length, breadth and height of a cuboid are in the ratio of 6: 4:3. If the total surface area
is 832 cm, find the volume of the cuboid.
5. Find the surface area of a cube whose volume is 3375 cm. Also find its diagonals.​

Answer 1

Answer:

5. Surface Area of cube = 1350 cm²

Step-by-step explanation:

5. Volume of cube = 3375 cm

   (side)³ = 3375

   side = ∛3375

   side = 15 cm

   Surface Area of cube = 6 (side)² = 6 × 15 × 15 = 1350 cm²
