a monument at a park is in the shape of a right square pyramid. a diagram of the pyramid and its net are shown.

what is the surface area of the monument?

enter the answer in the box.

m²

The surface area of the monument = 56 m^2

Step-by-step explanation:

A monument which is in the shape of square pyramid and the net is given.

The surface is nothing but the sum of areas of all the faces.

There are 4 congruent triangles on the sides and 1 square base.

Let's find the area of the base.

Area of the base = side *side

Here side = 4 m

Area of the base = 4*4 = 16 m^2

Now let's find the area of 1 triangle.

The base of the triangle is 4 and the height is 5.

Area of the triangle = 1/2*base * height

= 1/2*4*5

= 2*5

= 10 m^2

Area of the 1 triangle = 10m^2

We know the 4 triangles are congruent to each other.

Surface area = base area + 4(area of the triangle)

= 16 + 4(10)

= 16 + 40

The surface area of the monument = 56 m^2

Actually, it's 14.

Step-by-step explanation:

I took the test online in K12 and when I reviewed it said that 14 is the correct answer.

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
