Question

Tentukan luas permukaan dan volume bangun gabungan disamping!

pls bantuu:(​

Answer 1

Penjelasan dengan langkah-langkah:

p = 15 cm

l = 10 cm

t = 8 cm

tl = 16 – 8

tl = 8 cm

Lp = p×l + 2×(p+l)×t + (p+l)×tl

Lp = 15×10 + 2×(15+10)×8 + (15+10)×8

Lp = 150 + 400 + 200

Lp = 750 cm²

V = p × l × t × 4/3

V = 15 × 10 × 8 × 4/3

V = 50 × 32

V = 1.600 cm³

Answer 2

Luas Permukaan

P ( L ) + 2 ( p + l ) × t + ( p + l ) × tinggi limas

15 ( 10 ) + 2 ( 15 + 10 ) × 8 + ( 15 + 10 ) × 8

150 + 2 ( 25 ) × 8 + ( 25 ) × 8

150 + 50 × 8 + 200

150 + 400 + 200

550 + 200

750 cm²

_____________________

Volume

( p × l × t ) × 4/3

( 15 × 10 × 8 ) × 4/3

( 150 × 8 ) × 4/3

1.200 × 4/3

4.800/3

1.600 cm³
