tolong jawab plese no 27 29 pake cara(yang menjawab semoga dapat pahala amin :-)

3/4 - 1/6 = 7 L
3/4 - 1/6 = 9/12 - 2/12 = 7/12 ( 7/12 = 7 L , 1/12 = 1 L )
1 - 3/4 = 4/4 - 3/4 = 1/4 = 3/12 = 3 L [ B ]

rumus volume = segitiga ( alasnya ) × tinggi
1/2 × a × b × t = 336 cm3
1/2 × a × 6 × 8 = 336 cm3
a = 336 cm3 ÷ 1/2 ÷ 6 ÷ 8
a = 336 cm2 × 2 ÷ 6 ÷ 8
a = 14 [ B ]
