I don't know if I am correct or not, but I believe that you have to multiply the perimeter of your base and then multiply that by the height of your cube.

So in this case, you would do 4 x 4, since a cube is basically 6 squares, and a square has 4 sides.

4 x 4 = 16

Then the height is 4 as well.

16 x 4 = 64² (I believe you have to square the total as well, so don't forget that.)

If I am incorrect, please let me know. But I really do hope this helped. :)

Find the area of the figure below, formed from a triangle and a parallelogram.

ale4655 [162]

Answer:

Total área: 9+9+8+6= 32 mm^2

Step-by-step explanation:

Square = 3x3 = 9mm^2

Triangle= Heigh: sqrt (3^2+3^2) = 9 and base=3

A = (9x3)/2 = 9mm^2

Rectangle= 4x2= 8mm^2

Triangle (high: 5-2=3)

(4x3)/2 = 6mm^2

in a square garden plot (with an area of 400 sq ft)deer fencing priced at $1.50 per foot is to be installed around the plot. if

mina [271]

We have a square garden of 400 square foot.

The area of a square is:

$A=x^2$

where x: side length.

In this case:

$\begin{gathered} A=400=x^2 \\ x=\sqrt[]{400}=20\text{ ft} \end{gathered}$

The perimeter of the square is the sum of the lengths of the sides of the square. As they are all equal, we can write:

$P=4x=4\cdot20=80\text{ ft}$

The fencing is priced at $1.50 per foot. If we add the 7% sales tax to this price we get:

$C=1.50\cdot(1+0.07)=1.50\cdot1.07=1.605\text{ \$/ft}$

The fencing will be installed in all the perimeter (80 ft).

We can calculate the total cost by multiplying the sales price ($1.605 per foot) and the perimeter (80 ft):

$F=C\cdot P=1.605\frac{\text{\$}}{\text{ft}}\cdot80\text{ ft}=\$128.40$

Answer: the fencing will cost a total of $128.40
