Answer:

6 units

Step-by-step explanation:

The questions states that the area = perimeter.

From this we can set up an equation:

$x*y=2x+2y$

Since we know one of the sides is 3 we can substitue one of the variables for 3. In this case I choose $y$

$3*x=2x+2*3\\3x=2x+6$

Solving for x we get $x=6$ .

That's our answer!

Answer:

120

Step-by-step explanation:

volume of triangular prism = area of base times length

the base is a triangle and the area of a triangle can be calculated by using this formula

$a=\frac{bh}{2}$

where b = base length and h = height

Dimensions of base

base length = 8cm and height = 3cm

Thus,

$A=\frac{3*8}{2} \\3*8=24\\\frac{24}{2} =12\\$

The length of the triangular prism is 10cm

Thus volume = 10 * 12 = 120
