Jawab:
diketahui : panjang alas segitiga (a) = 10 cm.
tinggi segitiga (t) = 6 cm
volume prisma = 240cm3
ditanya :tinggi prisma= ... cm
penyelesaian :
Mencari luas alas segitiga
laΔ= 1/2 a x t
= 1/2 x 10 x 6
= 30
volume prisma tegak segitiga = luas alas x tinggi
240 = 30 x t
8 = t
jawabannya = c. 8 cm
Jawaban:
la = 1/2 × a × t
la = 1/2 × 10 × 6
la = 1 × 5 × 6
la = 30 cm
v = la × t
240 = 30 × t
t = 240 ÷ 8
t = 8 cm (opsi C)
