S.No.	Objects	l	b	h	Volume (cubic units)
1.	Brick	6 cm	8 cm	10 cm	—
2.	Windowpane	3 cm	—	45 cm	900 cubic cm
3.	Sunshade	70 cm	20 cm	—	4200 cubic cm
4.	Steps	80 cm	—	20 cm	32000 cubic cm
5.	Room	—	4 m	3 m	36 cubic m

Answer 1

S.No.	Objects	l	b	h	Volume (cubic units)
1.	Brick	6 cm	8 cm	10 cm	6 × 8 × 10 = 480 cubic cm
2.	Windowpane	3 cm	`900/(3 xx 45) = 20/3 = 6 2/3` cm	45 cm	900 cubic cm
3.	Sunshade	70 cm	20 cm	`4200/(70 xx 20)` = 3 cm	4200 cubic cm
4.	Steps	80 cm	`32000/(80 xx 20)` = 20 cm	20 cm	32000 cubic cm
5.	Room	`36/(4 xx 3)` = 3 m	4 m	3 m	36 cubic m
