If the cube with a 26√3 cm diagonal is melted then how tall is the height of the cuboid, if the length of the cuboid is equal to the arm of the cube, and the width of the cuboid is 13 cm? (in cm)

If the cube with a 26√3 cm diagonal is melted then how tall is the height of the cuboid, if the length of the cuboid is equal to the arm of the cube, and the width of the cuboid is 13 cm? (in cm) Correct Answer 52

As we know,

The volume of cube = a3

The volume of cuboid = lbh

Diagonal of the cube = √3a

⇒ √3a = 26√3

⇒ a = 26

Length of the cuboid l = 26 cm

Let the height of the cuboid be h cm

Width of the cuboid b = 13 cm

According to the question

26 × 13 × h = 26 × 26 × 26

⇒ h = (26 × 26 × 26) / (26 × 13)

∴ h = 52 cm

What is the ratio of the volume of a cuboid to the volume of a cube? Statement I. The ratio of the height, breadth, and length of the cuboid is 1 : 2 : 3 and the total surface area of the cuboid is 352 cm2. Statement II. The total surface area of the cube is given to be 384 cm2. Statement III. The length of the cuboid is 3 times the height of the cuboid and 1.5 times the breadth of the cuboid. The difference between the length and the height of the cuboid is 8 cm.
