he size of the *gap* matters.

2) If you only have numbers, GUESSTIMATE! 13X12X29 is close to 15x10x30 – not exact but close. 15×10=150×30=450 cubic inches.. or 12x12x30 – that’s close too. 12×12=144*30= 144+144=288 + 144 = 432 cubic inches. Again,, close enough. I have no idea what the ‘right’ answer is because most of the time, the perfect answer doesn’t matter. unless the size of the *gap* matters. “
