An 8m long cuboidal beam of wood when sliced produces four thousand 1cm cubes and there is no wastage of wood in this process. If one edge of the beam is 0.5m, find the third edge.

A metal cube of edge 12cm is melted and formed into three smaller cubes. If the edges of the two smaller cubes are 6cm and 8cm, find the edge of the third smaller cube.

An edge of a variable cube is increasing at the rate of 10cm/sec. How fast the volume of the cube is increasing when the edge is 5cm long?

Three cubes, each with 8cm edge, are joined end to end. Find the total surface area of the resulting cuboid

Three cubes each with 8 cm edge are joined end to end. Find the total surface area of the resulting cuboid.

Four identical cubes are joined end to end to form a cuboid. If the total surface area of the resulting cuboid is 684cm^(2) , find the length of edge of each cube. Also, find the ratio between the surface area of the resulting cuboid and the surface area of a cube.

A rectangular field is 112 m long and 62 m broad. A cubical tank of edge 6 m is dug at each of the four corners of the field and the earth so removed is evenly spread on the remaining field. Find the rise in level.

A certain quantity of wood costs Rs 250 per m^(3) . A solid cubical block of such wood is bought for Rs 182.25. Calculate the volume of the block and use the method of factors to find the length of one edge of the cube.

A cuboidal wooden block contains 36\ c m^3 wood. If it be 4cm long and 3cm wide, find its height.
