D = sqrt(3s^2) where s is the length of the side. Solving for s,
<span>3s^2 = d^2 iff </span>
<span>s^2 = d^2 / 3 iff </span>
<span>s = sqrt(d^2 / 3) </span>
<span>= d / sqrt(3) or d sqrt(3) / 3 </span>
<span>Surface area of the cube = 6 s^2. Thus, </span>
<span>A = 6 (d / sqrt(3))^2 </span>
<span>= 6d^2 / 3 </span>
<span>= 2d^2 </span>
<span>Volume = s^3. Thus, </span>
<span>V = (d / sqrt(3))^3 </span>
<span>= d^3 / 3sqrt(3) </span>
<span>= d^3 sqrt(3) / 9</span>
Answer:
4/9
Step-by-step explanation:
3L /2 = 2/3 cross multiply expressions
9L = 4 divide both sides by 9
L = 4/9
Step-by-step explanation:
7x+22=2(5x+2)
7x+22=10x+4 (-7x)
3x+4=22 (-4)
3X=18 (divide by 3)
X=6 pencils
check if the number is correct
asha= 7*6=42 42+22 is 64
Lucy= 5*6=30 30+2 is 3264/32 is 2
asha= 7*6=42 42+22 is 64Lucy= 5*6=30 30+2 is 3264/32 is 2there fore asha sells twice as many as Lucy
