Find the surface area of the triangular prism

765 m squared

Step-by-step explanation:

We need to find the area of all the sides of this 3D shape. We see that we have 3 rectangles and 2 triangles.

Rectangles:

We see that one rectangle (the leftmost one) has dimensions of 11 meters by 15 meters, so its area is 11 * 15 = 165 m squared.

The biggest rectangle is the one facing us, and its dimensions are 20 by 15, so the area is 20 * 15 = 300 m squared.

The last rectangle is on the bottom with dimensions of 15 m by 12 m, so the area is 15 * 12 = 180 m squared.

Adding these together, we get: 165 + 300 + 180 = 645 m squared.

Triangles:

These two triangles are actually congruent. Their base is 12 m, and their height is 10, so one triangle's area is 12 * 10 * (1/2) = 60. Since there are two, we multiply 60 by 2: 60 * 2 = 120 m squared.

Now, add the areas together: 645 + 120 = 765 m squared.

Hope this helps!

C) 765 m²

Step-by-step explanation:

(20×15) + (12×15) + (11×15) + 2(½×12×10)

765 m²

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
