Question

Deepak painted three closed containers to prevent them from rusting. a cubical container of edge 30cm, a cultural container of length 50cm, breadth 25cm and height 45cm and a cylindrical drum of radius 70cm, height 1m. find the total area painted ​

Answer 1

$\huge\frak\purple{solution}$

Deepak painted closed containers= 3

Edge of cubical container = 30 cm

Length of cubical container = 50 cm

Breadth of cubical container = 25 cm

Height of cubical container = 45 cm

Cylindrical drum radius = 70 cm

Cylindrical drum height = 1 m

Here we have to find the total area painted = 30 + 50 + 25 + 45 = 145

145 + 70 × 1 = 2465

There fore, 2465
