A right rectangle prism is 6 cm by 14 cm by 5 cm what is the surface area of the right prism
NeX [460]

Answer:

\large\boxed{S.A.=368\ cm^2}

Step-by-step explanation:

The formula of a surface area of a rectagular prism:

S.A.=2(lw+lh+wh)

l - length

w - width

h - height

We have the dimensions 6cm × 14cm × 5cm. Substitute:

S.A.=2(6\cdot14+6\cdot5+14\cdot5)=2(84+30+70)=2(184)=368\ cm^2

The median of the following data will ________________________ when you in add a data value of 1? (DO MATH on paper!) 8, 9, 9, 4
svlad2 [7]

Answer:

B decrease

Step-by-step explanation:

First, lets put the numbers in order from greatest to least.

10 9 9 8 6 4 4

Second, let's find the median without number 1. (The median is in bold.)

10 9 9 8 6 4 4

Third, let's add the number 1.

10 9 9 8 6 4 4 1

Fourth, let's find the median with the number 1.

10 9 9 8 6 4 4 1

Since there are two numbers in the middle let's find the average between them.

8+6=14

14/2= 7

Last, let's compare the two medians.

8>7

So when you add the number 1 the median decreases. So your answer is B decrease
