In the diagram, the rectangular solid has side lengths $1 \mathrm{~m}, 20 \mathrm{~cm}$ and $50 \mathrm{~cm}$. The volume of the solid, in cubic centimetres, is
(A) 170
(B) 7000
(C) 1000000
(D) 100000
(E) 10000

In centimetres, the dimensions of the box are $20 \mathrm{~cm}, 50 \mathrm{~cm}$, and $100 \mathrm{~cm}$ (since $1 \mathrm{~m}$ equals $100 \mathrm{~cm}$ ).

Therefore, the volume of the box is

$$
(20 \mathrm{~cm}) \times(50 \mathrm{~cm}) \times(100 \mathrm{~cm})=100000 \mathrm{~cm}^{3}
$$

ANSWER: (D)
