Answer:
WIDTH ‘W’ = 8 in; LENGTH = 11 in AND HEIGHT = 6 in
Step-by-step explanation:
VOLUME = (W+3)*(W-2)*W = 52
W*(W^2 +W - 6) = 525
SOLUTION BY TRIAL & ERROR
TRIAL 1 : LET W = 5; 5(25+5–6) = 120
TRIAL 2 : LET W=10; 10(100+10–6) = 1040
TRIAL 3 : LET W = 8; 8(64+8–6) = 528 OK
ANSWER WIDTH ‘W’ = 8 in; LENGTH = 11 in AND HEIGHT = 6 in
