Answer:
544 units²
Step-by-step explanation:
The surface area is the sum of the areas of the three rectangular faces and the two triangular bases.
SA = 10×14 +10×14 +12×14 + 2(1/2)(12)(8)
= 14×(10+10+12) +12×8
= 448 +96
= 544 . . . . square units
_____
The area of a rectangle is the product of its dimensions:
A = LW
The area of a triangle is half the product of its base and height:
A = (1/2)bh
Here, both triangles have the same area, so we multiplied the area of one of them by 2 to get the area of both of them.

Answer:
$94
Step-by-step explanation:
Let the price of a bowl, a pan and a dish be $b, $p and $d respectively.
14b +9p +12d= 135 -----(1)
10b +6p +8d= 88 -----(2)
Subtracting equation (1) with equation (2):
14b +9p +12d -(10b +6p +8d)= 135 -88
Expand:
14b +9p +12d -10b -6p -8d= 47
4b +3p +4d= 47
Multiply both sides by 2:
8b +6p +8d= 47(2)
8b +6p +8d= 94
Thus, the price of 8 bowls, 6 pans and 8 dishes is $94.
