Question

two cubes each of volume 125cmcube are joined0end to end together find t.s.a of resulting cuboid

Answer 1

volume of cube = a^3
therefore , a = 5cm
therefore the length of cuboid= 10cm
breadth = 5cm and height = 5cm
TSA of cuboid = 2(lb + bh + hl)
= 2(50+25+50)
= 2X125
=250cm^2

Answer 2

Answer:

Step-by-step explanation:

Volume of cube=a³

=(125)³

=5

Then the side of cuboid = 5,5,10

Then total surface area of. Cuboid=2(lb+bh+hl)

2(5×10+5×10+5×5)

2(50+50+25)

2(125)

=250 answer
