Answer:

Cube's features;

6 sides to a cube

All side lengths are equal, so all areas are the same

Given this information, we must find the area of one side and multiply that area by 6 since there are 6 equal sides of the same area.

Formula for area of square:-

A = a^2

A = a · a

Where 'a' represents the length of one side.

Plug in values;

A = a^2

A = 7^2

A = 49 centimetres is the area of one side.

Now we find the areas of all sides (6 sides in total);

49(6)

= 294 is the surface area of the cube.

Answer:

In a cube, the length and width are the same, so both sides will be 7 cm, yielding an area of 49 square centimeters.

Answer:

$f(x)=(x-3)^2-7$

Step-by-step explanation:

Use the formula:

$x^2+bx+c \implies (x+\frac{b}{2})^2-(\frac{b}{2}{)^2+c$

$f(x) = x^2 - 6x + 2$

$\implies f(x)=(x-\frac62)^2-(\frac62)^2+2$

$\implies f(x)=(x-3)^2-3^2+2$

$\implies f(x)=(x-3)^2-9+2$

$\implies f(x)=(x-3)^2-7$

What is the area of the base?

MAXImum [283]

Answer:

24 in²

Step-by-step explanation:

Hello there!

the figure shown is a triangular prism

The base is the triangle

So we need to find the area of the triangle using this formula

$A=\frac{bh}{2}$

where b = base and h = height

The base (triangle) has a base length of 8 inches and a height of 6 inches

Having found the information we needed, we plug it into the formula

$A=\frac{6*8}{2} \\6*8=48\\\frac{48}{2} =24\\A=24in^2$

So the area of the base is 24 in²
