find the volume (in m^3) of each of the following cube whose edges are (a) 8.4 cm (b) 1.4 m (C) 2 dm 5cm
Answers
Step-by-step explanation:
(A) a = 8.4 CM
volume of cube = a^3
= (8.4)^3
= 592.704 cube CM
= 592.704/1000000
= 0.000592704 CM cube
(B) a = 1.4 CM
VOLUME OF CUBE = a^3
= (1.4)^3
= 2.744 cube CM
= 2.744/1000000
= 0.000002744 CM cube
(C) since, 1 dm (decidecimeter) = 10 CM
2 dm 5cm = 2(10) + 5
= 25 CM
a = 25 CM
VOLUME OF CUBE = a^3
= (25)^3
= 15625 CM cube
= 15625/1000000
= 0.015625
