Answer 2

Answer:

(i) 105a⁷b⁴

(ii) 64p²q³r

Step-by-step explanation:

volume of cuboid (rectangular box) = lbh

(i) given,

l = 5ab

b = 3a²b

h = 7a⁴b²

volume = lbh

= 5ab × 3a²b × 7a⁴b²

= 5×a×b×3×a×a×b×7×a×a×a×a×b×b

= 5×3×7×a×a×a×a×a×a×a×b×b×b×b

= 105×a⁷×b⁴

= 105a⁷b⁴

(ii) given,

l = 2pq

b = 4q²

h = 8rp

volume = lbh

= 2pq×4q²×8rp

= 2×p×q×4×q×q×8×r×p

= 2×4×8×p×p×q×q×q×r

= 64×p²×q³×r

= 64p²q³r

hope it helps.
