Find the surface area of the triangular prism
melomori [17]

Answer:

608 ft²

Step-by-step explanation:

<u>1) Find the area of the bases</u>

A=\frac{1}{2} bh where b is the base length and h is the height

Plug in b and h

A=\frac{1}{2} (12)(8)\\A=48

Multiply the answer by 2 (because there are 2 bases)

A=96

Therefore, the area of the two bases is 96 ft².

<u>2) Find the area of the two sides facing up</u>

A=lw where l is the length and w is the width

Plug in l and w

A=10*16\\A=160

Multiply the answer by 2 (because there are 2 sides)

A=320

Therefore, the area of these two sides is 320 ft².

<u>3) Find the area of the bottom side</u>

A=lw where l is the length and w is the width

Plug in l and w

A=12*16\\A=192

Therefore, the area of this side is 192 ft².

<u>4) Add all the areas together</u>

96 ft² + 320 ft² + 192 ft²

= 608 ft²

Therefore, the surface area of the triangular prism is 608 ft².

I hope this helps!

What is the equation in point slope form of the line that passes through the point
ch4aika [34]

Point-slope form:  y - y₁ = m(x - x₁)

[m is the slope, x₁ and y₁ ---> (x₁, y₁) is the point]

Since you know:

m = 5

(2, 6) = (x₁, y₁)       Substitute/plug in the values into the equation

y - y₁ = m(x - x₁)

y - 6 = 5(x - 2)   The 1st option is your answer
