Question

Question 2. Two cubes, each of volume 1331 cm* are joined end to end. Find volume and surface area of resulting cuboid thus formed.
​

Answer 1

Answer:

volume of each cube- 1331

＝ a3＝1331

＝ a＝11

therefore side of each cube is 11cm

therefore, length of cuboid is ＝11+11＝22cm

breadth＝11cm

height＝11cm

volume of cuboid ＝ l*b*h

＝ 22*11*11＝2662cm3

surface area of cuboid＝2(lb+bh+hl)

＝2(22*11+11*11+11*22)

＝2*605＝1210cm2

Step-by-step explanation:

Answer 2

Answer:

The surface area is $1210cm^{2}$ and volume is $2661cm^{3}$

Step-by-step explanation:

It is given that two cubes, each of volume $1331 cm^{3}$ are joined end to end.

We need to determine the volume and surface area of cuboid formed.

Considering one cube,

the volume is $a^{3} =1331$

$a=11cm$

If they are joined, volume will be $2*1331=2661cm^{3}$

Surface area of resulting cuboid is $2(lb+bh+hl)$

$=2(22*11+11*11+11*22)$

$=1210cm^{2}$
