1: 5·7·2=70 A volume 13·2·7=182 B volume 70+182=252 total volume so the first statement is false just change the numbers to 5,7,2 2: 2·2·2=8 the middle cube volume 15·15·2=450 outside cube volume 450-8=442 total volume so the third statement is false it should be 442 3: 3·8·12=288 rectangle volume 6·12·3/2=108 triangle volume 288+108=396 total volume so the second statement is false it should be 108
