Question

two cubes each of volume 64 cm cube are joined end to end. find the surface area of the resulting cuboid​

Answer 1

Answer:

Step-by-step explanation:

Volume of both cubes is 64cm^3

Therefore one side= (64)^1/3

                                 = 4

Since the cubes are joined end to end

Length = 8cm breadth = 4cm

height= 4 cm

Surface area of resulting cuboid=

2(lb + bh +hl)

2(32+16+32)

160 cm^2

Answer 2

Answer:

According to question

side^3 = 64 (vol.)

side = 4 cm

T.S.A. of cuboid =

2(lb + BH + hl)

2(32+16+32)

2(80)

160cm^2
