4. Find the volume of the
trapezoidal prism.

216 m³

Step-by-step explanation:

let's calculate the area of the front face and then multiply it by 4m

11*3 + (11-4)*3

(left and right triangle equal a rectangle area here)

= 33 + 21

= 54

multiplied by 4

-> 216

the last step is like multiplying with height in other exercises and other bodies

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
