Question 7
Answer:
I don't know what's happening, but thanks for free points. :)))
Step-by-step explanation:
Are the dimensions 8yd x 8yd x 8yd? If so this is how you do:
First calculate the area or one side. Then multiply it by 6 as all the sides of the cube have the same area.
Side area = 8yd x 8yd = 64yd^2
Surface area = 6 x 64yd^2 = 384yd^2
Step-by-step explanation:
3x+6=18
3x=18-6
3x=12
x=4
