I’ll answer, but wait, do I send a picture of my work? or not? It says I have to make a table of values, so
17 - 6 x 10 ÷ 2 + 12 = 17 - 60 ÷ 2 + 12 = 17 - 30 + 12 = -13 + 12 = -1
I think the length is 17.75cm and the width is 12.75 cm
I'm not entirely sure whether it's the smallest possible length but it works on the calculator
17.75*2+12.75*2=61
288m^3 is what I got, hope it helps!
