Answer 1

1. l sgtg = 1/2 × a × t
= 1/2 × 8 × 15
= 60 dm2
vol. = l alas × t
=60 dm2 × 19 dm
=1140 dm3

2. l sgtg = 1/2 ×16×30
= 240 dm2
vol = 240 dm2×41dm
=9840 dm3

3. l sgtg = 1/2 × 0,7 × 24
= 8,4 m
vol = 8,4m × 29m
=243,6 m3
atau= 243600 dm3

4. l sgtg = 1/2 × 25 × 48
=600 cm2
vol = 600 × 56
=36000 cm3

5. l sgtg = 1/2 × 13 ×17
= 110,5 cm2
vol = 110,5 × 22
=2431 cm3

Answer 2

Volume prisma=1/2×alas×t×tinggi prisma

1.v=1/2×8×15×19=1.140dm kubik
2v=1/2×16×30×41=9.840 kubik
3v=1/2×0,7×24×29=243,6m kubik
4.v=1/2×25×48×56=58.800 cm kubik
5v=1/2×13×17×12=1.326cm kubik
