Surface area for a cuboid of length, l, bredth, b and height h.
= 2*(lb + bh + lh)
for 15 by 7 by 4 1/2 = 15 by 7 by 4.5
Surface area = 2*(15*7 + 15*4.5 + 7*4.5)
= 2*(105 + 67.5 + 31.5)
=2 *(204) = 408
Surface area of box = 408 in²
Answer:
-1/2
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
1
6 = 3x - 9 ( add 9 to both sides )
15 = 3x ( divide both sides by 3 )
5 = x
2
x + 4 < 1 ( subtract 4 from both sides )
x < - 3
3
+ 3 = - 5
Multiply terms on both sides by 2
x + 6 = - 10 ( subtract 6 from both sides )
x = - 16
