Answer:
(i) 21a⁷b⁴
(ii) 8p²q³r
Step-by-step explanation:
(i) Given dimensions
= 5ab , 3a²b & 7a⁴b²
∴ Volume = 5ab × 3a²b × 7a⁴b²
= (5 × 3 × 7)(a × a² × a⁴)(b × b × b²)
= 21 × a⁷ × b⁴
= 21a⁷b⁴
(ii) Given dimensions
= 2pq , 4q² , 8rp
∴ Volume = 2pq × 4q² × 8rp
= (2 × 4)(p × p)(q × q²)(r)
= 8 × p² × q³ × r
= 8p²q³r
