Given:
The shape is square.
To find:
The surface area and volume of a square.
Explanation:
The length of each side of the square is "a" units.
The formula for the surface area of the square is,

The formula for the volume of the square is,

Using these formulas, we can find the surface area and the volume of the square that has side length "a" units.
For example:
Let the side length of 3cm for a square.
So, the dimensions are 3cm by 3cm by 3cm.
That is,
The Length is 3cm.
The breadth is 3cm.
The height is 3cm.
So,

The surface area of the square is,

Therefore, the surface area of the square is 54 square cm.
The volume of the square is,

Therefore, the volume of the square is 27 cubic cm.
Answer:
y= -11
Step-by-step explanation:
After rearranging equation 2, we get x= y+3/2
Sub it into equation 1
y= 3(y+3/2) + 1
y= 3y+9/2 + 1
y= 3y + 11 / 2
2y = 3y + 11
-y = 11
y = -11
Answer:
True
Step-by-step explanation:
True.
The solution to a system of equations is the point where two equations intercept. In both cases, we can see that the interception of the two systems shown occurs at (0, 1). So the statement is correct.
let's notate it with letters to I can notate it in this problem
the plus is P
the circle is C
the square is S
the smiley face is F (for face)
the triangle is T
in all, we see that:
circle can't be next to the smiley face or the triangle or the square so it must be at the end next to to the plus sign but we don't know if it is at the right end or the left (____P C or C P____)
plus is not next to smiley face or triangle, so it must be next to the square (___S P C or C P S___)
triangle is to the right of the square, so we have to choose the guess that has an empty space to the right of the square, so it has to be C P S T __
then the last shape is the smiley face which goes in the last space
so the order is C P S T F or circle, plus, square, triangle smiley face
