Step-by-step explanation:

we are given a triangle

and we want to figure out the missing exterior angle of the triangle

in order to so

remember

the straight line theorem

therefore we get:

cancel 72° from both sides:

recall that,

if a side of a triangle is extended then exterior angle so formed equal to the sum of the two opposite interior angles

so we acquire:

simplify addition:

this is answer of 144 cubic meters
