Answer: 2908.92435 inches.
Step-by-step explanation for shape 1: A = 2(wl + hl + hw) = 2 · (30 · 13 + 13 · 13 + 13 · 30) = 1,898 inches.
Step-by-step explanation for shape 2:
Using the formulas:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A:
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=9·30+13·30+9·30+1
2·﹣94+2·(9·13)2+2·(9·9)2﹣134+2·(13·9)2﹣94≈1010.92435
Step-by-step explanation for total volume: 2908.92435 inches.

Answer:
5x - (x/y) = 18 when x=4 and y=2
Step-by-step explanation:
5x - (x/y)
When x=4 and y=2
Substitute the value of x=4 and y=2 into the expression
5x - (x/y)
5(4) - (4/2)
Multiply 5 by 4 and divide 4 by 2
=20 - 2
Subtract 2 from 20
=18
5x - (x/y) = 18 when x=4 and y=2
