HEY MATE,

A single Brick volume is 15 cm³

Now, Total bricks here are ( 4 × 4 ) + ( 3 × 3 ) + ( 2 × 2 ) + 1

Total Bricks = 16 + 9 + 4 + 1 = 30

Total volume of platform = ( 15 × 30 ) cm³ = 450 cm³ ANS_✔️

THANK YOU...✌️

single brick volume 15cm³✅

• base of platform contains= 4 × 4 = 16 bricks
• middle of platform contains = (3×3) + (2×2) = 13
• upper most layer of platform contains only 1 brick.

Total bricks = 16 + 13 + 1 = 30 bricks

The volume of platform = 30 × 15 = 450cm³
