480 = (6)(8)(T)
48T = 480
T = 480/48
T =10 cm
Luas permukaan = 2PL + 2LT + 2PT
(=) 2(6)(8) + 2(8)(10) + 2(6)(10)
(=) 96 + 160 + 120
(=) 376 cm²
p . l . t = 480 cm³
6 . 8 . t = 480 cm³
48t = 480 cm³
t = 480/48
t = 10 cm
Luas permukaan = 2 (pl + lt + pt)
= 2 (6 x 8 + 8 x 10 + 6 x 10)
= 2 (48 + 80 + 60)
= 2 x 188
= 376 cm²
