Which of these has the SAME formula s³, where s is the side?

Volume of a cube. Volume of a cube = s³. TSA of a cube = 6s², area of a square = s², perimeter of a square = 4s.

Which of these has the SAME formula $s^{3}$ , where $s$ is the side?

Volume of a cube =

s^{3}

. TSA of a cube =

6 s^{2}

, area of a square =

s^{2}

, perimeter of a square = 4

s

Answer: A) Volume of a cube

**Volume = length × breadth × height =

l \times b \times h

.**

For a cube:

V = s^{3}

.

Units: if

l, b, h

are in cm,

V

is in

cm^{3}

. If in

m, V

is in

m^{3}

. **Always check units before computing.** Mixing

m

and cm gives nonsense.

Example: cuboid

4 \times 5 \times 3

cm.

V = 60 cm^{3}

. Cube of side 7 cm:

V = 343 cm^{3}
