a rectangular piece of metal is 25 in longer than it is wide. squares with sides 5 in long are cut from the four corners and the flaps are folded upward to form an open box. if the volume of the box is 1980 in ^3, what were the original dimensions? please provide steps for answer

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

answer: idk wbu

step-by-step explanation: umm..

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

the correct answer would be c
