Fill up the gap.
If each side of a cuboid is doubled the volume of the cuboid become ........... time.

Find the volume of the following cuboids.

If each edge of a cube is doubled, how many times will its volume increase?

Fill up the gap. The shape of a glass (tumbler) is usually in the form of ............ of a cone.

Fill up the gap. The curved surface area of a cone is also called the ...........

Take a sheet of paper. Measure its area. Pile up such sheets of paper of same size to make cuboid. Measure the height of this pile. Find the volumne of the couboid by finding the product of the area of the sheet and the height of this pile of sheets. This activity illustrates the idea that volume of a solid can ve deduce by thsi method also (if the base and top of the solid are congruent and parallel to each other and its edges are perpendicular to the base). Can you think of such objects whose volumne can be found by using this method?

Find the surface area of a cuboid formed by placing three cubes of side 5 cm on one another.

Four squares of side 8cm each were cut out from the four corners of a rectangular metal sheet of size 48cmxx36cm .Find the volume of the open cuboid formed with the remaining portion of the metal sheet.

Under a constant pressure head, the rate of flow of orderly volume flow of liquid through a capillary tube is V. if the length of the capillary is doubled and the diameter of the bore is halved, the rate of flow would become
