Penjelasan dengan langkah-langkah:
A. Volume Keduanya
-
B. Selisih volume
C. Luas Permukaan
Lp Milik Nana:
Lp Milik Lecy:
panjang = 8 cm
lebar = 9 cm
tinggi = 10 cm
panjang = 6 cm
lebar = 8 cm
tinggi = 9 cm
v = p × l × t
= 8 × 9 × 10
= 720 cm³
=============
Lp = 2 × (pl + pt + lt)
= 2 × ((8 × 9) + (8 × 10) + (9 × 10))
= 2 × (72 + 80 + 90)
= 2 × 242
= 484 cm²
= 6 × 8 × 9
= 432 cm³
==============
= 2 × ((6 × 8) + (6 × 9) + (8 × 9))
= 2 × (48 + 54 + 72)
= 2 × 174
= 348 cm²
v. balok nana - v. balok lecy
= 720 cm³ - 432 cm³
= 288 cm³
