Penjelasan dengan langkah-langkah:

• Diagonal 1 = 16 cm
• Diagonal 2 = 21 cm
• Tinggi Limas = 30 cm
• Volume Limas = ? cm³

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \colorbox{yellow}{ \sf{Volume Limas}}[/tex]

[tex]\sf{V_{Limas}}[/tex] = [tex]\sf{⅓ × L_{Alas} × T_{Limas}}[/tex]

[tex]\sf{V_{Limas}}[/tex] = [tex]\sf{⅓ × (½ × d_{1} × d{2} ) × T_{Limas}}[/tex]

[tex]\sf{V_{Limas}}[/tex] = [tex]\sf{⅓ × (\cancel{½} × \cancel{16}⁸× 21) × 30}[/tex]

[tex]\sf{V_{Limas}}[/tex] = [tex]\sf{⅓ × (8 × 21) × 30}[/tex]

[tex]\sf{V_{Limas}}[/tex] = [tex]\sf{⅓ × 168 × 30}[/tex]

[tex]\sf{V_{Limas}}[/tex] = [tex]\sf{⅓ × 5.040}[/tex]

[tex]\sf{V_{Limas}}[/tex] = [tex]\underline{\boxed{\red{\bf{1.680~cm³}}}}[/tex] (?)
