Answer:
1. B
2. B
Here are my answers.
1. a. 592 square inches
2. a. 208 square inches
3. SA = 248 square feet
Step-by-step explanation:
1. solve for the Surface Area of a box.
SA = 2 (lw + lh + wh)
SA = 2 [(12)(8) + (12)(10) + (8)(10)] = 2(96+120+80) = 2(296)
SA = 592 inches²
so. a. 592 square inches
2. solve for the Surface Area of a box.
SA = 2 [(8)(4) + (8)(6) + (4)(6)] = 2(32+48+24) = 2(104)
SA = 208 inches²
so: a. 208 square inches
3. SA = 2 (lw + lh + wh)
SA = 2 [(10)(6) + (10)(4) + (6)(4)] = 2(60+40+24) = 2(124)
SA = 248 feet²

SA = 2 [(8)(4) + (8)(6) + (4)(6)] = 2(32+48+24) = 2(104)
SA = 208 inches²
so: a. 208 square inches
3. SA = 2 (lw + lh + wh)
SA = 2 [(10)(6) + (10)(4) + (6)(4)] = 2(60+40+24) = 2(124)
SA = 248 feet²
