Penjelasan dengan langkah-langkah☁

Nomor 5

t = v : l alas

= 1.785 : 105

= 17 dm

Nomor 6

V kubus = S³

= 15³

= 3.375

V balok = 15 × V kubus

= 15 × 3.375

= 50.625 cm³

Nomor 7

Panjang 1 rusuk kubus = 56:4 = 14 cm

V = S³

= 14 × 14 × 14

= 2.744 Cm³

Nomor 8

V = S³

S = ³√1.331

= 11 cm

Nomor 9

V = S³

S = ³√216

= 6 dm

Nomor 10

t balok = 1.632

———

17 × 8

= 1.632

———

136

= 12 cm

Nomor 11

V balok = 12 × 8 × 18 = 1.728

r kubus = ³√1.728 = 12

Nomor 12

V kubus + V balok

= s³ + p × l × t

= 10³ + 14 × 10 × 17

= 1.000 + 2.380

= 3.380 cm³

Nomor 13

t balok = 1.512 : 126 = 12 dm

Nomor 14

V balok = 5 × v kubus

= 5 × 10³

= 5 × 1.000

= 5.000 cm³

Nomor 15

V kubus

= S³

= 10³

= 1.000 cm³
