To find the area of one side of the cube, you multiply the length by width. 16•16=256. Then you multiply that by the number of sides of the Cubs. 256•6=1536. The surface area should be 1536ftsq.
Answer:
x=18
Step-by-step explanation:
2/3x=12
2/3x=36/3 (simplified)
3* 2/3x=3* 36/3 (gets rid of denominator)
2x=36
(2x)/2=36/2 (getting rid of 2)
x=18 (answer by isolatinf variable)
Answer D
Step-by-step explanation:
Answer:
So let us call the shorter side, i.e the width: 'x'
So each length is four times the width = 4x
The perimeter consists of two widths and two lengths and equals 50 inches.
So:
x+x+4x+4x=50
solve for x:
10x = 50
to find x divide both sides by 10:
10x/10 = 50/10
x=5
So width equals 5 in and length is four times this i.e. 4x5=20
To check: 5+5+20+20=50 !!!!
