Answer

Measurement is a process of comparison of the given unknown quantity with a fixed known quantity of the same kind called the unit.

Card 2Length

What is the S.I. unit of length, and how is length measured?

Answer

Length is the distance between two points. Its S.I. unit is metre (m). It is measured with a metre ruler or a measuring tape.

Card 3Mass

What is the S.I. unit of mass, and which instrument measures mass?

Answer

Mass is the quantity of matter contained in a body. Its S.I. unit is kilogram (kg). It is measured using a beam balance or an electronic balance.

Card 4Time

What is the S.I. unit of time, and which instruments measure time?

Answer

Time is the interval of occurrence of an event. Its S.I. unit is second (s). It is measured with a pendulum clock, watch, stop-clock, or stop watch.

Card 5Temperature

What is the S.I. unit of temperature, and which instrument measures it?

Answer

Temperature measures the hotness or coldness of a body. Its S.I. unit is kelvin (K). Other common units are degree Celsius and degree Fahrenheit. It is measured using a thermometer.

Card 6Volume of cube

Find the volume of a cube with side 4 cm.

Answer

Given: side = 4 cm Formula: Volume of a cube = (one side)^3 Step 1: Volume = (4 cm)^3 Step 2: Volume = 4 cm × 4 cm × 4 cm Step 3: Volume = 64 cm^3 Answer: 64 cm^3…

Card 7Volume of cuboid

Find the volume of a cuboid with length 10 cm, breadth 5 cm, and height 2 cm.

Answer

Given: length = 10 cm, breadth = 5 cm, height = 2 cm Formula: Volume of a cuboid = length × breadth × height Step 1: Volume = 10 cm × 5 cm × 2 cm Step 2: Volume = 100 cm^3 Answer: 100 cm^3…

Card 8Volume of cylinder

Find the volume of a cylinder with radius 3 cm and height 10 cm. Use π = 3.14.

Answer

Given: radius = 3 cm, height = 10 cm, π = 3.14 Formula: Volume of a cylinder = π × (radius)^2 × height Step 1: Volume = 3.14 × (3 cm)^2 × 10 cm Step 2: Volume = 3.14 × 9 cm^2 × 10 cm Step 3: Volume = …
