Question

panjang rusuk alas = 12cm
tinggi Limas = 8cm
tentukan:
1.) luas permukaan Limas
2.)Volume limas​

Answer 1

Jawab:

1. LP Limas = 336 cm2

2. V. Limas = 384 cm3

Penjelasan:

1. Luas alas ( La ) = 12 × 12 = 144 cm2

alas = rusuk = 12 cm

LP limas = La + ( 1/2 × alas × tinggi )

= 144 + ( 1/2 × 12 × 8 )

= 144 + ( 2 × 96 )

= 144 + 192

= 336 cm2

2. V. Limas = 1/3 x Luas alas ( La ) x Tinggi

= 1/3 x 144 x 8

= 1/3 x 1152

= 384 cm3
