carilah luas dan volumenya, tolong dijawab besok dikumpul

Lprisma = 2Lalas + Kalas ×t
= 2×1/2×12×16 + 4×10 ×20
= 192 + 40 ×10
= 192 + 400
= 592

Vprisma= Lalas × t
= 1/2×d1×d2 × 20
=1/2×12×16 × 20
= 96 × 20
= 1920

Lp= 2 x luas alas + keliling alas x tinggi
= 2 x ( (12 x 16) / 2 ) + 2(10 + 10) x 20
= 2 x 96 + 40 x 20
= 192 + 800
= 992 cm2

Vp = Luas alas x tinggi
= 96 x 20
= 1.920 cm3
