Question

luas Salah satu sisi kubus 162 cm².Volume kubus tersebut adalah?​

Answer 1

Penjelasan:

Diagonal bidang

= √162

= √81 . 2

= 9√2

Diagonal sisi =

r√2

9√2 = r√2

r = 9

Maka Volumenya

= s³

=9³

= 729 cm³

Answer 2

Penjelasan:

Diketahui:

Kubus, dengan:

• Luas satu sisi = 162 cm²
• L = s × s = s², sehingga [tex]\sf s = \sqrt{L}[/tex]
  => [tex]\sf s = \sqrt{L} = \sqrt{162} = 12,7 \ cm[/tex]

Ditanyakan:

Volume kubus?

Penyelesaian:

Rumus: [tex]\boxed {\boxed {\sf \bf V = s \times s \times s }}[/tex], sehingga:

Volume kubus tersebut
=> [tex]\sf \bf V = s \times s \times s = 12,7 \ cm \times 12,7 \ cm \times 12,7 \ cm = \underline {\boxed {\blue {\sf \bf 2.048,3 \ cm^3}}}[/tex]
