Answers
4:The formula for the volume of a sphere is V = 4/3 πr³.
5: If a solid object has an irregular shape, a stone, for example, its volume can be measured in two ways. One is by using a measuring cylinder, and the other one is by using an overflow jar.
Measurement of volume of irregular solid bodies both heavier and lighter than water including those soluble in water, by displacement of water or other liquids in a measuring cylinder.
study questions:
1 (a) Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
1(b) The derived SI unit for volume is the cubic meter based on the three dimensional use of the base unit for length, the meter. The more common metric unit for volume is the liter.
So, the SI unite of volume is
=m

1. (c) The sub multiples of volume are millilitre, centilitre and decilitre.
Their value in terms of SI system( litre) are:
1 millilitre= 0.001 litre
1 centilitre= 0.01 litre
1 decilitre= 0.1 litre
Submultiples are units which are smaller in magnitude than the SI unit.
Multiples are units which are greater in magnitude than the SI unit.
Example: kilolitre, hectolitre, decalitre.
2. (a ).
The unit for length in SI system is m,where match box having a length much less than m only in some cm claims it's dimension to be better represented in cm.
2 (b). Volume of matchbox(cuboid) is given by = l×b×h
Where l is the length b is breadth and h is height
Since all the dimensions are measured in meter (m)
So unit of volume is meter cube or m^3
