We are given with the volume of 32 cubic meters. The dimension of the box is obtained by taking the cubic root of 32 which is 3.1748 x 3.1748 x 3.1748 meters. When the dimensions are tripled, 9.5244 x 9.5244 x <span>9.5244 meters. The volume is a ) 864 cubic meters. </span>
For any inscribed quadrilateral, the opposite angles add to 180
(angle PMN) + (angle NOP) = 180
(8x-24) + (4x) = 180
12x-24 = 180
12x-24+24 = 180+24 ..... add 24 to both sides
12x = 204
12x/12 = 204/12 ..... divide both sides by 12
x = 17
angle NOP = 4x
angle NOP = 4*17
<h3>
angle NOP = 68 degrees</h3>
