joined such two cubic’s. The third place step is a cuboidal shape of 30cm length 30cm breadth and
15cm height. Find the surface area to paint the color for this podium except the base of the
Answers
We know that,
The respective surface areas of the front & back sides are equal.
So,
2 ( 30 × 30 + 30 × 30 + 30 × 30 + 30 × 15) cm^2
= 2 ( 900 + 900 + 900 + 450) cm^2
= 6300 cm^2
Now, the surface areas of the left and right sides are,
2 ( 30 × 60) cm^2
= 2 × 1800 cm^2
= 3600 cm^2
Also, the Surface area of the top side,
= 3 ( 30 × 30) cm^2
= 2700 cm^2
∴ total surface area = (6300 + 3600 + 2700) cm^2
= 12600 cm^2
Ans) 12600 cm² is the required surface area to paint the podium, except for the base

12600 cm² is surface area to paint the colour of this podium except the base of the podium
Step-by-step explanation:
Surface area front & back side are equal
= 2 ( 30 * 30 + 30*30 + 30 * 30 + 30 * 15)
= 2( 900 + 900 + 900 + 450)
= 6300 cm²
Surface area on Left and right side
= 2 ( 30 * 60)
= 2 ( 1800)
= 3600 cm²
Surface area on top
= 3 ( 30 * 30)
= 2700 cm²
surface area = 6300 + 3600 + 2700
= 12600 cm²
12600 cm² is surface area to paint the colour of this podium except the base of the podium
