It takes 5 shovels of sand to make 1 shovel of mortar so how many will it take to have 30 shovels of mortar? You can put this in a proportion.
5/1 = x/30
You don't need to worry about the cement since it's asking for sand.
Cross multiply and you get x·1 and 30·5. So this means you need 150 shovels of sand. x=150 when you multiply 30·5.
Step-by-step explanation:
ratio will be
30/27
= 10/9
=10:9
9^0 its that answer because all the other number you can make a whole number.
The answer is 114sqrt{6} in³
A regular hexahedron is actually a cube.
Diagonal of a cube D is a hypotenuse of a right triangle which other two legs are face diagonal (f) and length of a side (a):
D² = f² + a²
Face diagonal is a hypotenuse of a right triangle which sides are a and a:
f² = a² + a² =2a²
D² = f² + a²
f² = 2a²
D² = 2a² + a² = 3a²
D = √3a² = √3 * √a² = √3 * a = a√3
Volume of a cube with side a is: V = a³
D = a√3
⇒ a = D/√3
V = a³ = (D/√3)³
We have:
D = 8√2 in
