Find the volume of the figure.<br> 2.25 m<br> 4<br> m<br> 2.5 m<br> no
liberstina [14]

<u>Given</u>:

Given that the figure is a triangular prism.

The length of the prism is 4 m.

The base of the triangle is 2.5 m.

The height of the triangle is 2.25 m.

We need to determine the volume of the triangular prism.

<u>Volume of the triangular prism:</u>

The volume of the triangular prism can be determined using the formula,

V=\frac{1}{2}bhl

where b is the base of the triangle,

h is the height of the triangle and

l is the length of the prism.

Substituting b = 2.5, h = 2.25 and l = 4 in the above formula, we get;

V=\frac{1}{2}(2.5)(2.25)(4)

V=\frac{1}{2}(22.5)

V=11.25 \ m^3

Thus, the volume of the triangular prism is 11.25 m³

Help please can’t find this anywhere

Answer:

  x = 6

Step-by-step explanation:

You can actually work out the answer yourself.

The two angles shown have the total measure 168°, so the unmarked one is ...

  168° -100° = 68°

That is ∠WXZ, so we know ...

  68° = (5x +38)°

  30 = 5x . . . . . . . . . . divide by °, subtract 38

  6 = x . . . . . . . . . . . . .divide by 5
