Answer:
Below.
Step-by-step explanation:
a. Volume = area of triangular side * length
1/2 * 3 * 4 * 8
= 48 cm^3.
Surface area = 2 * area of the triangle + area of sloping side+ area of the base + area of the back side
= 2 * 1/2 * 3*4 + 5*8 + 3*8 + 4*8
= 12 + 40 + 24 + 32
= 108 cm^2.
b. Volume = area of the triangular side * length
= 1/2 * 5.0 * 5..0 * 8.2
= 12.5 * 8.2
= 102.5. cm^3.
Surface area = 2 * area of the triangle + 2 * area of a sloping side + area of the basee
= 2 * 1/2 * 5^2 + 2 * 5 * 8.2 + 8.2 * 7.1
= 25 + 82 + 58.22
= 165.22 cm^2.

Step-by-step explanation:
Answer:
Total cost of boots = $56.02
Step-by-step explanation:
$59 x 0.90 = $53.10
$53.10 x 1.055 = $56.02
or
59 x 0.10 = 5.9
59 - 5.9 = $53.10
53.10 x 0.055 = $2.92 tax
$53.10 + $2.92 = $56.02
