Answer:
1.46035
2.200
3. 236
Step-by-step explanation:
1. Formula: length x width x height
23x9x5=46035
2. Formula: triangle area (base x height / 2) x length
10 x 20 = 200
3. Formula: πr^2 x height
(5/2)^2 x 3.14 x 12 = 235.5 = 236
Answer and step-by-step explanation:
1. A=734
due to this stuff A=2(wl+hl+hw)=2·(9·23+5·23+5·9)=734
3. A≈227.77
due to this A=2πrh+2πr2=2·π·2.5·12+2·π·2.52≈227.76547
2. the other guy is right
