Assalamu’alaikum kaka” yg baikkk bisa gaa kerjain inii… yg nmr 1&2 ajaa…mksh sblmnya.

Materi : Bangun Ruang Sisi Datar

Soal Nomor 1

Volume

V = p × l × t + sisi² × t + ⅓ × sisi² × tL

V = 24.10.22 + 10².8 + ⅓ × 10² × 2√14

V = 528.10 + 100.8 + ⅓.100.2√14

V = 5.280 cm³ + 800 cm³ + 200/3√14 cm³

V = ( 6.080 + 66⅔√14 )cm³

Luas Permukaan

tst = tinggi sisi tegak

Lp = 2( pl + pt + lt ) + 4( st ) + s² + 4.½.s.tst

Lp = 2( 14.10 + 24.22 + 10.22 ) + 4( 10.8 ) + 2.10.9

Lp = 2( 140 + 528 + 220 ) + 4( 80 ) + 2( 90 )

Lp = 2( 360 + 528 + 160 + 90 )

Lp = 2( 450 + 688 )

Lp = 2( 1.138 cm² )

{ Lp = 2.276 cm² }

Soal Nomor 2

Volume

V = p × l × t + ½ × a × t × tp

V = 24 × 30 × 40 + ½ × 24 × 9 × 30

V = 24 × 1.200 cm² + 108 cm² × 30 cm²

V = 28.800 cm³ + 3.240 cm³

{ V = 32.040 cm³ }

Luas Permukaan

Lp = 2( pt + lt ) + ( a + 2s ) × tp

Lp = 2( 24.40 + 30.40 ) + ( 24 + 2[15] ) × 30

Lp = 2( 960 + 1.200 ) + ( 24 + 30 ) × 30

Lp = 2( 2.160 cm² ) + 720 cm² × 30

Lp = 4.320 cm² + 21.600 cm²

{ Lp = 25.920 cm² }
