tinggi sisi tegak = t
t² = 8² + 3²
t² = 64 + 9
t² = 73
t = √73
luas limas = luas alas + 4 x luas sisi tegak
= (6 x 6) + (4 x 1/2 x 6 x √73)
= 36 + 12√73 cm²
semoga membantu ya :)
4s = 24
s = 6cm
t bid tegak = √t² - (s/2)² = √8² + 3² = √64 + 9 = √73
Lp = La + 4. Luas bid tegak
Lp = s² + 4. 1/2 a . t bid tegak
Lp = 6² + 2 . 6 . √73
Lp = (36 + 12 √73 ) cm²
