Tolong di jawab ya kak ^_^
Penjelasan dengan langkah-langkah:
1. a. diket :
- p = 12 cm
- l = 8 cm
- t = 6 cm
ditanya :
- luas sisi balok =….?
jawab :
l = 2 (pl + pt + tl)
= 2(12cm×8cm) + (12cm×6cm) + (6cm×8cm)
= 2 (96cm + 72cm + 48cm)
= 2 (216cm)
= 432 cm³
b. diket :
- p = 15 cm
- l = 12 cm
- t = 8 cm
ditanya :
- luas sisi balok =…?
jawab :
l = 2 (pl + pt + tl)
= 2(15cm×12cm) + (15cm×8cm) + (8cm×12cm)
= 2 (180cm + 120cm + 96cm)
= 2 (396cm)
= 792 cm³
2. a. diket :
- p = 12 cm
- l = 8 cm
- t = 6 cm
ditanya :
- volume balok =…?
jawab :
v = p x l x t
= 12cm x 8cm x 6cm
= 576cm³
b. diket :
- p = 15 cm
- l = 12 cm
- t = 8 cm
ditanya :
- volume balok =…?
jawab :
v = p x l x t
= 15cm x 12cm x 8cm
= 1.440 cm³
