Answer 1

volume limas :

= ⅓ × La × t

= ⅓ × 5 × 5 × 11 - 5

= ⅓ × 25 × 6

= 25 × 2

= 50 cm³

volume kubus :

= s × s × s

= 5 × 5 × 5

= 125 cm³

volume total :

= v kubus + v limas

= 125 cm³ + 50 cm³

= 175 cm³

Answer 2

Jawaban:

bangun ruang

ukuran sisi kubus = 5 cm dan ukuran pada Limas segiempat= alas nya yg berbentuk persegi dgn sisi 5 cm dan tinggi = 11cm - 5cm = 6 cm

Volume gabungan:

Vol.kubus + Vol.limas segiempat= (s³) + (1/3 x luas alas x tinggi) = (5cm)³ + (1/3 x sisi x sisi x tinggi) = 125cm³ + (1/3 x 5cm x 5cm x 6cm) = 125cm³ + (25cm² x 2cm) = 125cm³ + 50cm³ = 175 cm³ , Opsi (C)
