Question

two cubes together form a cuboid each cube is volume of 729 find the total surface area of cuboid




please answer​

Answer 1

Answer:

T.S.A. of cuboid=810cm²

Step-by-step explanation:

Volume of cube=a³

729=a³

a=³√729

a=9cm

l=9+9=18, b=9, h=9

T.S.A. of cuboid

=2(lb+bh+hl)

=2(18×9+9×9+9×18)

=2(162+81+162)

=2(405)

=810cm²
