What is the volume of the following prism?

ira [324]

Answer: $\Large\boxed{B.~\displaystyle 75~m^3}$

Step-by-step explanation:

Given information

Height = 2 m

Base = 5 m

Length = 15 m

Given the formula for Triangular Prism Volume

$V~=~\displaystyle \frac{1}{2}\times ~b~\times~h~\times~l$

$\to V=Volume\\\to b=base\\\to h = height\\\to l = length$

Substitute values into the formula

$V~=~\displaystyle \frac{1}{2}\times ~(5)~\times~(2)~\times~(15)$

Simplify by multiplication

$V~=~\displaystyle \frac{5}{2}~\times ~30$

$\Large\boxed{V~=~\displaystyle 75~m^3}$

Hope this helps!! :)

Is the line through points p(-3,-2) and Q(2,3) perpendicular to the line through points R(10,1) and S(15,-6)?

Katen [24]

The slope of line PQ is m1 = ( 3 - (-3) ) / (2 - (-2) ); then m1 = 6/4 = 3/2;
In the same way, the slope of line RS is m2 = -7/5;
But (3/2) x (-7/5) = -21/10, which is diferrent from - 1;
So, the lines aren't perpendicular.

May someone answer this please? also no explanation no brainliest

miss Akunina [59]

Surface area is 62 units ^2

5 x 2 = 10 since there are 2 of these side double it (20)

3 x 2 = 6 since there are 2 of these side double it (12)

3 x 5 = 15 since there are 2 of these side double it (30)

20 + 30 + 12 = 62
