Question

5 - mathematical knowledge
what is the volume of a cube with edge lengths of 7 cm?
a 84 cm³
b 147 cm³
c 294 cm³
d 343 cm³

Explanation:

Step1: Recall the formula for the volume of a cube

The volume \(V\) of a cube is given by \(V = s^{3}\), where \(s\) is the length of an edge.

Step2: Substitute the given edge length into the formula

Here, \(s = 7\ cm\). So, \(V=7^{3}\).

Step3: Calculate \(7^{3}\)

\(7^{3}=7\times7\times7 = 343\).

Answer:

D. \(343\ cm^{3}\)
