Question

If a cube has a surface area of 6 cm? its volume must be 6 cm3 1 cm3 O 18 cm3 O 3cm3 none of the above

Answer 1

The volume of a cube formula is V = X³.

So, to find the volume we need the value of X. Where X is length of one edge.

In the question we have surface area is 6 cm².

Generally, the formula for surface area is

Surface area = 6X².

Now by using this information we can calculate the volume of cube by the following steps. Hence, the answer is option (2).

Given, surface area = 6 cm² 2 6x² = 6 cm C: formula of surface area = =C 6x2) Now cancelling 6 on both sides -> x² = lama By squaring on both sides a) x² x 2 = vi om? x = 1cm, substitute the value of x in volume Formula (w= x3) 3 N = 1 = 1x1x1 v=1cm 3 1 cm Thus volieme of cube is Scanned with CamScanner
