So each house can hold 1000 cubes that are 1 meter in length. The house is also shaped like a cube, so you need to cube-root 1000. The cube-root of 1000 is 10. So the cube house has a length, width, and height of 10 meters.

The problem is giving us the total volume of each house (1000 unit cubes), and is asking us for the dimensions of the cube house.

We can solve this using the volume equation for the cube:

Volume_{cube} =Side_{cube} ^{3}

we solve for side (edge) which is what we look for

Side_{cube}=\sqrt[3]{Volume_{cube} }

Side_{cube}=\sqrt[3]{1000 unit cubes }\\Side_{cube}=10 unit cubes

like it is said in the problem the cube has the same dimensions for all three edges so the house would be 10 unit cubes high, 10 unit cubes deep and 10 unit cubes long

Ali was swimming along the bottom of his backyard pool at a depth of 6 feet then he pushed off the bottom and rose 4 feet what i
olga nikolaevna [1]

Answer:

2 feets

Step-by-step explanation:

Given that :

Alli's Initial depth = 6 feets

Number of feets in which Alli rose = 4 feets

Alli's new position relative to the surface of the pool:

Difference of Alli's initial depth and feets risen :

6 feets - 4 feets = 2 feets

Hence, Alli is now 2 feets below the surface of the pool.

A pole-vaulter uses a 15-foot-long pile. She grips the pole so that the segment below her left hand is twice the length of the s
Shalnov [3]
Let x + 1.5 be length of segment above left hand
Let 2x be length of segment below left hand

15 = x + 1.5 + 2x
15 = 3x + 1.5
15 - 1.5 = 3x
13.5 = 3x
13.5/3= 3x/3 
4.5 = x
x = 4.5
This is the length above the left hand. 

2x must be then 4.5*2 = 9 foot
This is the length below the left hand. 

Checking
4.5 + 9 + 1.5 = 15 foot 

Adding length below left hand & length of left hand to right hand:
9 + 1.5 = 10.5
The right hand is hence 10.5 foot far up the pole.

3/4 ÷ 1/2 what is the answer to this
Maksim231197 [3]
Dividing by a half is the same as multiplying by two. 3/4 multiplied by 2 is
1 \frac{1}{2}
or, in improper fraction form
\frac{3}{2}
or, in decimal form, 1.5

What is the solution of the system of equations c + 4d = 8 and c = 4d - 6
Tema [17]
Rewrite the second equation in same form as the first So we have

c + 4d = 8

c - 4d = -6     Now add:-

2c + 0 = 2
2c = 2

c = 1  

Now substitute c = 1 in the first equation:-

1 + 4d = 8
4d = 7

d =  7/4  = 1 3/4

Answer c = 1 and d = 1 3/4  Answer
