Use the formula V = s³, where V is the volume and s is the edge length of the cube, to solve this problem.
Varvara68 [4.7K]
Given that volume is:
V=s³
where:
s=side length
The volume of a cube whose side length, s=3/4 yards will be given by:
V=(3/4)³
Simplifying this we get:
V=27/64 yd³

Answer: 27/64 yd³

The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
Igoryamba

Answer:

A

Step-by-step explanation:

Joint variation is given by:

y=kxz

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

360=k(4)(10)

Solving for k:

40k=360\Rightarrow k=9

Therefore, our equation is:

y=9xz

Then when x = 5 and z = 12:

y=9(5)(12)=540

The answer is A.
