  • Length of the edge
    Find the length of the edge of a cube with a cm2 surface and a volume in cm3 expressed by the same number.
  • Water level
    How many cm will the water level in a cube-shaped tank with an edge of 3 m drop if we discharge 189 hl of water?
  • Wooden container
    The locksmith should cover the cube-shaped wooden container with a metal sheet inside. The outer edge of the container is 54cm. The wall thickness is 25 mm. The container has no lid. Calculate. How many sheets will be needed to cover it?
  • Two cubes
    The surfaces of two cubes, one of which has an edge of 22 cm longer than the second are differ by 19272 cm2. Calculate the edge length of both cubes.
  • Cube surface and volume
    The surface of the cube is 500 cm2, how much cm3 will be its volume?
  • Calculate 3
    Calculate the cube volume whose edge is 3x-1,3x-1,3x-1
  • The volume 2
    The volume of a cube is 27 cubic meters. Find the height of the cube.
