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.

Answer:
4/11
Step-by-step explanation:
Outcomes that meet your requirement are
(1, 6), (2, 6), (6, 1), (6, 2)
for a total of 4 favorable outcomes.
There are 11 outcomes in which one die shows a 6.
So your probability would be 4/11.
Answer:
x=3, y=8; (3,8)
Step-by-step explanation:
To use the substitution method, first solve for a variable.
2x+y=14
2x+y(-2x)=14(-2x)
y=14-2x
Now substitute y in the other equation with 14-2x
5x-2(14-2x)= - 1
Simplify by multiplying inside the parenthesis.
5x-28+4x= - 1
Combine the x values
9x-28= - 1
9x=27
x=3
Now substitute the x value in to solve for y
2(3)+y=14
6+y=14
y=8
Answer:
f(3) = - 18
Step-by-step explanation:
To evaluate f(3) , substitute x = 3 into f(x) , that is
f(3) = - 4(3 + 1) - 2 = - 4(4) - 2 = - 16 - 2 = - 18
