Fill in the blanks

(a)

The volume of a cube of side 1 cm is equal to .....m³

Answer

10⁻⁶

(b)

The surface area of a solid cylinder of radius 2.0 cm and height 10.0 cm is equal to ...(mm)²

Answer

1.5×101.5 \times 10⁴

(c)

A vehicle moving with a speed of 18 km h⁻¹ covers...m in 1 s

Answer

5

(d)

The relative density of lead is 11.3. Its density is .....g cm⁻³ or .....kg m⁻³.

Answer

11.3, 11.3×1011.3 \times 10³

Explanation

These questions test unit conversion skills. For (a), converting cm to m requires cubing the conversion factor. For (b), the cylinder's total surface area includes both circular ends and the curved surface, with all measurements converted to mm. For (c), converting km/h to m/s involves dividing by 3.6. For (d), relative density is the ratio of a substance's density to water's density (1 g/cm³), making the conversion straightforward.
