The volume of a cube is 125 cm cube. (i) Find the length of its edge.
(ii) Find its surface area.

(i) 5 cm

(ii) 150 cm²

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

it has the same slope and a different y-intercept

hope this : )
