What is the height of a solid box that has a mass of 438 g, a destiny of 2.17 g/cm, a length of 40 cm, and a width of 20 cm.
1 answer:
<em>h ≈ 0.25 cm</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
- <u><em>density formula</em></u>
<em>d = m/V</em>
<em>V = l×w×h</em>
<em>replace</em>
<em>2.17 = 438/(40×20)×h</em>
<em>2.17 = 438/800×h</em>
<em>2.17×800×h = 438</em>
<em>1736h = 438</em>
<em>h = 438/1736</em>
<em>h ≈ 0,25 cm</em>
<em>Good luck !</em>

84 gallons/(2.8 gpm) = 30 minutes
Area = length * width
5/8 = 10 * width
width = (5/8) / 10
width = 1 / 16
width = 0.0625 inches

Answer:
1/2
Step-by-step explanation:
8(1/2)^4
= 8 * 1 / 2^4
= 8/(2*2*2*2)
= 8/16
= (8*1) / (8*2)
= 1/2
