Answer 1

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
