Explanation / Answer
3. V = (1/2)bhl (l is lenght) = (1/2)(8)(6)(17) = 408 in3 SA = (2)(1/2)(8)(6) + (17)(8) + (17)(6) + (17)(62+ 82) = 48 + 136 + 102 + 170 = 456 in2 4. V = (4/3)r3 =(4/3)(5)3 = 523.3 m3 SA = 4r2 = 4(5)2 = 314m2 5. V = lwh = (11)(7)(4) = 308 cm3 SA = 2(11)(7) + 2(11)(4) + 2(7)(4) = 154 + 88 +56 = 298 cm2 6. V = (1/3)r2h = (1/3)(9)2(15) =1271.7ft3 SA = r2 +r(r2 + h2)=(9)2 + (9)(92 +152) = 254.34 + 494.55 = 748.9 ft27. V =r2h = (2)2(9) = 113in3 SA = 2r2 + 2rh =2(2)2 + 2(2)(9) = 25.12 + 113 = 138in2 8. V = (15)(15)(6) + (15)(3)(3) = 1350 + 135 = 1485in3 SA = (6)(15) + (15)(15) +(15)(9) + (15)(3) + (15)(3) + (15)(12) + 2(15)(6) + 2(3)(3) = 918in2
