Tolong yg baik hati dibantu plisss

Answer 1

3. a. Vp = La x t
V = (1/2 x 21 x 8) x 30
V = 84 x 30 = 2520cm³
b. Lp = (2 x La) + Luas jmlh sisi tgak
Lp = (2 x 84) + (30 x { 15 + 10 + 6 + 8})
Lp = 168 + 1170 = 1338cm²

5. a. Vp = La x t
V = (1/2 x 30 x 16) x 40
V = 240 x 40 = 9600cm³
b. Lp = (2 x La) + Luas jmlh sisi tgak
Lp = (2 x 240) + ({40 x 17} x 4)
Lp = 480 + 2720 = 3200cm²
