What is the height of the triangular prism below if the volume equals 1,638 cubic millimeters?

1 answer:

5 0

Volume of the prism is the area of the triangle x the height.

To find the height find the area of the triAngle first, then divide the volume by the area.

Area = 1/2x 7x18 = 63 square mm

X = 1638/63

X = 26 mm

Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Step-by-step explanation:

The sum of the measures of interior angles of a polygon with $n$ sides is given by:-

$(n-2)\times180^{\circ}$

Given: The sum of the measures of the interior angles of a polygon is 1920°.

i.e. $(n-2)\times180^{\circ}=1920^{\circ}$

$n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67$

But number of sides cannot be in decimal.

Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
