Answer:
3.375
Step-by-step explanation:
The amount of material it took to build the cube is the same as the surface area. Since a cube has 6 congruent faces we can divide to find the area of one face.
13.5/6 = 2.25m.
2.25m is the area for each face of the cube.
Each face is square and has an area of 2.25m. To find the length of each side of the square we can take the square root. The square root of 2.25 is 1.5. The length of each side of the square is 1.5 metres.
To find the volume of the cube, we can use the formula V = lwh.
V = lwh
V = 1.5*1.5*1.5
V = 3.375
The volume of the giant sugar cube is 3.375m.
3.5,
since 3350/670 = 5, we know that the 2345.0/670 = 3.5
Answer:
Step-by-step explanation:
2x - y + z = 4
4x - 2y + 2z = 8
-x + 3y - z = 5
2x - y + z = 4
-x + 3y - z = 5
x + 2y = 9
4x - 2y + 2z = 8
-2x + 6y - 2z = 10
2x + 4y = 18
x + 2y = 9
2x + 4y = 18
-2x - 4y = -18
2x + 4y = 18
0 =0
