Question

a block of wood has a length of 4 cm, a width of 5 cm, and a height of 10 cm. what is the volume of the wood?
20 cm³
19 cm³
50 cm³
200 cm³

Explanation:

Step1: Recall volume formula

The volume $V$ of a rectangular - prism (which the block of wood is) is given by $V = l\times w\times h$, where $l$ is length, $w$ is width and $h$ is height.

Step2: Substitute values

Given $l = 4$ cm, $w = 5$ cm and $h = 10$ cm. Then $V=4\times5\times10$.

Step3: Calculate the result

$4\times5\times10=(4\times5)\times10 = 20\times10=200$ $cm^{3}$.

Answer:

D. 200 $cm^{3}$
