Answer:

Step-by-step explanation:

To find the mean of a set of numbers, add all the numbers together. Then, divide the sum by how many numbers you had to begin with.

Add the numbers together:

10 + 12 + 15 + 11

= 48 This is the sum of the data

Count how many numbers you had:

10, 12, 15 and 11 are FOUR numbers (amount of data).

Divide the sum of the data by the amount of data.

48 ÷ 4 = 12 This is the mean

The mean of 10, 12, 15, 11 is 12.

Find the surface area of the triangular prism. 15.6 cm 10 cm 11 cm 12 cm

dimulka [17.4K]

Answer:

533.6cm²

Step-by-step explanation:

Hello!

I'm here to answer your question!

Area of each triangular base:

$\frac{1}{2}(12)(10)=60$

Area of the rectangular faces:

$12\times 11 =132$

$15.6\times 11=171.6$

$10\times 11=110$

Add to find the surface area:

$60+60+132+171.6+110=533.6$

Thus, the surface area of the triangular prism is = 533.6 yd²

Hope this helps you!

Hugs from,

How to find the volume

aev [14]

Answer: 1.44 centimeters cubed.

Step-by-step explanation:

To find the volume of a rectangular prism, use the following formula:

$V=whl$ , where w equals the width, h equals the height, and l equals the length.

Substituting 0.6, 1, and 2.4 for the variables:

V = 0.6 * 1 * 2.4

V = 1.44 cm^3

The volume of the prism is 1.44 centimeters cubed.
