A triangular prism is 20 millimeters long and has a triangular face with a base of 24 millimeters and a height of 16 millimeters

uysha [10]

Answer:

The surface area of the prism is $1,664\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to

$SA=2B+PL$

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the triangular prism

<em>Find the area of the triangular face B</em>

$B=\frac{1}{2}(24)(16)= 192\ mm^{2}$

<em>Find the perimeter of the triangular face P</em>

$P=(24+20+20)= 64\ mm$

we have

$L=20\ mm$

substitute the values

$SA=2(192)+(64)(20)=1,664\ mm^{2}$

Why is the approximate perimeter of a semi circle with a radius of 8 m?

RUDIKE [14]

Circumference of a circle with radius 8 =
c = 2 pi 8
For semi circle we will divide this by 2 and then add the base segment which is the length of the radius * 2.
p = (2 * 3.14 * 8)/2 + 16
perimeter = 41.12 m
