Answer:
3cm
Step-by-step explanation:
you divide 18cm by 6cm and get the volume.
Consider the right angles triangle with hypotenuse 15 and leg 8 cm formed by drawing the diagonal.
The other leg (x) will be the other side of the rectangle and , by Pythagoras we have:-
15^2 = 8^2 + x^2
x^2 = 225 - 64
x^2 = 161
x = 12.69 cms
So the perimeter p = 2*8 + 2* 12.69
= 16 + 25.38
= 41.38 cms (answer)
