Answer:
x = 32, that is for solving for x
Answer: 120 in
Step-by-step explanation: You have to multiply all the numbers. Remember length.width.height is how you get your answer. .=multiply
The only thing that we have to do in this problem is to
convert the units.
We know that:
1000 g = 1 kg
100 cm = 1 m
Therefore:
density = (2.7 g / cm^3) * (1 kg / 1000 g) * (100 cm /
m)^3
<span>density = 2700 kg / m^3</span>
Half of 126 = 63, which is the sum of 1 length and 1 width.
<span>since length = 6 times width, then 63 = 7 * width. or, 63/7 = 9 is width. </span>
<span>9*54 = 10*54 - 54 = 540 - 54 = 486 </span>
<span>to use a formula, knowing that length = 6w you'd have </span>
<span>126=2*(w+6w) </span>
<span>126 = 2*7w </span>
<span>w=126/2*7 = 63/7 = 9 </span>
<span>area = 9*54 = 486</span>
