    Question

    The dimensions of a cuboid are length = 8 cm, breadth =

    5 cm, and height = 3 cm. Find its volume and total surface area.
    A Volume = 128 cm┬│, Total surface area = 188 cm┬▓ Correct Answer Incorrect Answer
    B Volume = 120 cm┬│, Total surface area = 158 cm┬▓ Correct Answer Incorrect Answer
    C Volume = 100 cm┬│, Total surface area = 358 cm┬▓ Correct Answer Incorrect Answer
    D Volume = 220 cm┬│, Total surface area = 258 cm┬▓ Correct Answer Incorrect Answer

    Solution

    Volume = l ├Ч b ├Ч h = 8 ├Ч 5 ├Ч 3 = 120 cubic cm Total Surface Area (TSA) = 2(lb + bh + hl) = 2[(8 ├Ч 5) + (5 ├Ч 3) + (3 ├Ч 8)] = 2[40 + 15 + 24] = 2 ├Ч 79 = 158 sq cm Answer: Volume = 120 cm┬│, Total surface area = 158 cm┬▓
