Answer the 4 th one
on lapaer good handwritting​

Answer 1

Answer:

Given:

l=8m

w=7.5m

h=6m

We need not write this in the paper, my friend!

For better understanding, let's draw a cube (I used ms paint, see fig below)

Here, EFGH is excluded. We need to find the outer surface area of the cube elcluding EFGH, i.e., A=(Total surface area)-(Area of EFGH)

A=(2lw+2lh+2hw)-(lw) [Where l=lenght, w=width, h=height]

A=lw+2hl+2hw [Take 2 common from 2hl+2hw to make our calculation easy ]

A=lw+2(hl+hw)

A=8×7.5+2(7.5×6+6×8)

A=60+186

A=246m³ [Never forget the units]

So, harshit painted 246m³ of a box.

HOPE THIS HELPS :D
