Question

A cuboid has a volume of 3000cm3

, with height 15cm and length 20cm.

Find the area of the upper surface

Answer 1

Answer:

Volume of a Cuboid=L*B*H

B=V/ (L*H)

B=3000/(20*15)

B=3.33

area of upper surface=L*B

area of upper surface=20*3.33

........................................=66.6 or  67 square m

Step-by-step explanation:

Answer 2

Answer:

200 $cm^2$

Step-by-step explanation:

Volume (V) = l*b*h = 3000 $cm^{3}$

Length (L)= 20 cm

Height (H)= 15 cm

Breadth = V/(L*H)

             =3000/(20*15)

             =3000/300

             =30/3 = 10

Now, area of upper surface = l*b

                                              = 20*10

                                              = 200

Therefore, area of the upper surface = 200 $cm^2$
