enter your answer in the box.
cm²

The surface area of cube with side measure 11 cm  is 726 cm²

Step-by-step explanation:

Given : A cube with side measure 11 cm

We have to find the surface area of the given cube.

We know the surface area of cube is

Where a is the side measure of cube.

Since, given cube has side = 11 cm

Thus, the surface area of cube is

On simplifying, we get,

Thus, The surface area of cube with side measure 11 cm  is 726 cm²

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
