The net of the triangular prism is shown below
What is the surface area of the right triangular prism?

A. 624
B. 816
C. 912
D.864

the surface area of the right triangular prism is 864 . Correct option D. 864

Step-by-step explanation:

Here we have The net of the triangular prism is shown below . We need to find What is the surface area of the right triangular prism . Let's find out:

We have two same triangles  , with area =

⇒        { 2 is multiplied as there are 2 triangles }

⇒  

Now ,   We have 3 rectangles two of which are same have parameters as :

So , area of two rectangles

⇒

⇒

⇒

And area of other rectangle is :

⇒

⇒

⇒

So , total area = 288+480+96=864

Therefore , the surface area of the right triangular prism is 864 . Correct option D. 864

(D) 864 cm²

Explanation:

Given:

Base, b = 12cm

Height, h = 8 cm

Hypotenuse, s = 10cm

Length, l = 24 cm

Surface area, A = ?

We know:

Surface area = bh + 2ls + lb

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

c.   x=2.4cm

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.
