Question

Volume bangun tersebut adalah..

Answer 1

V total=V limas+V prisma

V prisma=L alas x tinggi
=(1/2 x 2 x 2) x 20
=2 x 20
=40

V limas= 1/3 x L alas x tinggi
=1/3 x (1/2 x 2 x2) x 9
=6

V total=46 

Answer 2

Volume dibagi dua.

Volume 1 = Volume Prisma
= Luas alas x Tinggi
= 1/2 [at] x Tinggi
= 1/2 [2 x 2] x 20
= 2 x 20
= 40 m³

Volume 2 = Volume limas
= 1/3 x Luas Alas x Tinggi
= 1/3 x 1/2 x [2 x 2] x 9
= 2 x 3
= 6 m³

Sehingga, volume total:
= 40 + 6
= 46 m³
