Volume = 13.824 cm³
A. Berapa panjang sisi kubus?
B. Berapa cm² luas alas kubus?
[tex]\sf \bf \sf v = s³[/tex]
[tex]\sf \bf \sf 14.824= s³[/tex]
[tex]\sf \bf \sf \sqrt[3]{13.824}= s[/tex]
[tex]\sf \bf \sf 24 \: cm = s[/tex]
[tex]\sf \bf \sf luas \: alas = 6 × s²[/tex]
[tex]\sf \bf \sf luas \: alas = 6 × 24²[/tex]
[tex]\sf \bf \sf luas \: alas = 6 × (24×24)[/tex]
[tex]\sf \bf \sf luas \: alas = 6 × 576[/tex]

a.) 24 cm
b.) 576 cm²
Penjelasan dengan langkah-langkah:
a.) s = ³√V
s = ³√14.824
s = 24 cm
b.) L = s × s
L = 24 × 24
L = 576 cm²
