24.)

L = 2(p×l + p×t + l×t)

= 2(10×6 + 10×5 + 6×5)

= 2(60 + 50 + 30)

= 2 × 140

= 280cm² (D)

25.)

V1 = p × l × t = 10 × 6 × 4 = 240cm³

V2 = La × t

= ½ × a × t × t.prisma

= ½ × 4 × 6 × 10

=120cm³

V. gabungan =240 + 120 = 360cm³ (D)

Jawaban:

2x(PxL + LxT+ PxT)

2x(10×6 + 6×5 + 10×5)

2x(60 + 30 + 50)

2×140 = 280

V = PxLxT

V =10 x 6 x 4

V = 240 Cm³

V = (1/2 x a x t) x t

V = (1/2 x 4 x 6) x 10

V = 12 x 10

V = 120 Cm

240 + 120 = 360

maaf kalo salah
