Answer:
Step-by-step explanation:
Volume
V = B * h
B = 1/2 a * b
Solution
Area of Triangles = B = 1/2 * 6 * 8
Area of Triangles = B = 24 square inches
Volume = B * H
Volume = 24 * 12
Volume = 288 cu in
Surface Area
Triangles
Area of one triangle = 24 square inches [ See Above ]
Area of two triangles = 48 square inches
Left Side
Area = L * W
L = 12
W = 8
Area = 12 * 8
Area = 96
Right side
Area = L * W
L = 12
W = 6
Area = 12 * 6
Area = 72
Area Back
L = 12
W = 10
Area = 12 * 10
Area = 120
Total = 120 + 72 + 96 + 48 = 336 square inches
