$\approx 2744 cubic cm$ $~~2744" cubic cm"$

Explanation:

A cube has $6 square faces$ $color(blue)"6 square faces"$

The area of 1 face = $\frac{1175}{6} \approx 195.83 square cm$ $1175/6~~195.83" square cm"$

The area of a square $= l^{2}$ $=l^2$ where $l$ $l$ is length of side.

$\Rightarrow l = \sqrt{195.83} \approx 14 cm$ $rArrl=sqrt195.83~~14"cm"$

The volume of a cube $= l^{3}$ $=l^3$

$\Rightarrow volume \approx 14^{3} = 2744 cubic cm$ $rArr"volume "~~14^3=2744" cubic cm"$

$2740.5 c m^{3}$ $2740.5cm^3$

Explanation:

Surface area of a cube $6 \times a^{2}$ $6 xx a^2$

Given $6 a^{2} = 1175 c m^{2}$ $6a^2=1175cm^2$

$:.a^2=1175/6$

$:.a^2=195.833333$

$:.a=sqrt195.833333$

$:.a=13.99404635$

volume of a cube $=a*a*a or a^3$

$Volume=13.99404635^3$

$Volume=2740.500744cm^3$

$Volume=2740.5cm^3$
