Answer 1

43) IT COMPRISES OF 4 RECTANGLE AND IN CENTRE IT'S SQUARE OF SIDE 5 m

4 rectangle area= 4( 5×20)
= 4( 100)
=400

area of square = 5×5 = 25

so total area= 400+25= 425

44) cube volume= 6×6 ×6= 216

cuboid sides are= 6, 9+6,,20
= 6, 15,20

cuboid volume= 6×15×20= 1800

total volume = 1800+216= 2016
