Question

I need help for this question

Answer 1

The bottom of the box has lots of electrical force applied to it because of the amount of weight being pushed down

Answer 2

775

Explanation:

House area:

`A=bh+(1)/(2)bh+ (1)/(2)bh*2+bh\\A=(5*20)+((1)/(2) *5*5)+((1)/(2) *5*5)*2+(10*30)\\A=100+12.5+12.5*2+300\\A=550`

Porch area:

`A=bh-((1)/(2)bh+ (1)/(2)bh+ bh)\\A=(15*30)-((1)/(2)*5*5+ (1)/(2)*5*5+ 20*5)\\A=450-225\\A=225`

Both:

P= porch area

H= house area

`A=H+P\\A=550+225\\A=775`
