The perimeter is 2(length) + 2(width), so 2(x+5) + 2(x+4) = 42 m. In solving for x, you find 6. Plug 6 back into your length and width where x originally was, and you find your length to be 11m, and your width to be 10m. Hope this helps!
1 The volume of the cube is 2 * 2 * 2 or 2 ^ 3 in ^ 3 while the
volume of the large box is 10 * 10 * 10 or 10 ^ 3 in ^ 3.
2 The answer is 125. Just divide the large box to the volume
of the cube 1000 / 8 = 125.
3 The box will hold the same number of balls as small boxes.
With the balls, there is empty space.
4 The answer is still 125. Just find the volume of the box
and of the cube. Divide the box volume by the cube volume.
Probability of heads or tails is .5
so you do (.5)^3 and you get D = 0.125
Answer: 360ft
Explanation:
x = 18/1/20
x = 18 x 20
x = 360ft
