Answer:
7
Step-by-step explanation:
Total number of surfaces of cube are 6.
Each surface is square.
And area of square is (side)^2
That means, total surface area will be 6 * (side)^2
From question,
294 = 6 * (side)^2 ( Surface area given)
=> 294 ÷ 6 = ( side) ^2
=> 49 = side^2
=> √49 = side
=> 7 = side
So, length of edge of cube is 7
Answer:
6
Step-by-step explanation:
X by its self is always 1x
1x+8=-15 you have to get rid of 8 by subtracting on both sides
1x=-23 now get rid of 1 by dividing on both sides
x=-23
To solve this proportion:

Simplify 3/6, it reduces to 1/2

Then do the Criss cross method
1d = 7 ×2
d=14
Hope it helps!
Volume = length * width ( aka base ) * height
2 feet = 24 inches.
24*15*8=2880 inches.
