Question

Find the surface area of the right triangular prism below.

Answer 1

first try and solve for the hypotenuse...what do you get?

Answer 2

how do you do that?

Answer 3

\[c = \sqrt{a^2+b^2}\]
remember that thing?

Answer 4

oh, yes! so do i plug in 3, 4 and 8 into that
so 8= sqroot 3sq+4sq

Answer 5

no...

Answer 6

8 is not part of the right triangle

Answer 7

you're going to look for that last side of the triangle

Answer 8

only then can you solve tis

Answer 9

oh. i get it now 3sq +4sq=csq

Answer 10

yup

Answer 11

so solve for c

Answer 12

its 5, now what?

Answer 13

To find the surface area of a right triangular prism we must use this formula:

SA = wh + lw + lh + ls
w = width
h = height
l = length
s = side
now find hypoteneus of triangle 3^2 +5^2 = h^2
hyp will be 5 ad now plug values

Answer 14

\[SA = h(a+b+c) + ab\]

Answer 15

where a = 4
b = 3
c = 5
h = 8

Answer 16

108!

Answer 17

seems so

Answer 18

could you help me with another one? please

Answer 19

hmm ill try

Answer 20

Find the value of x in the figure below if the volume is 232,789.58 mm3.

Answer 21

use the formula \[V = \frac{bah}{2}\]
where b (base) = 24.5
a (altitude) = what you're looking for
h (height) = 75.4
v = volume
