∻Solution by Steps∻ ‖ step 1 ⋮ To find the surface area of the cuboid, we use the formula: $ \text{Surface Area} = 2(lw + lh + wh) $ where $ l $ is the length, $ w $ is the width, and $ h $ is the height. ‖ ‖ step 2 ⋮ Substituting the given dimensions: $ l = 106 \, \text{cm}, w = 38 \, \text{cm}, h = 40 \, \text{cm} $ into the formula gives us: $ \text{Surface Area} = 2(106 \times 38 + 106 \times 40 + 38 \times 40) $. ‖ ‖ step 3 ⋮ Calculating each term: $ 106 \times 38 = 4028 $, $ 106 \times 40 = 4240 $, and $ 38 \times 40 = 1520 $. Thus, $ \text{Surface Area} = 2(4028 + 4240 + 1520) $. ‖ ‖ step 4 ⋮ Adding these values: $ 4028 + 4240 + 1520 = 9788 $. Therefore, $ \text{Surface Area} = 2 \times 9788 = 19576 \, \text{cm}^2 $. ‖ ∻Answer∻ ⚹ 19576 cm² ⚹ ∻Key Concept∻ ⚹ The surface area of a cuboid is calculated using the formula $ 2(lw + lh + wh) $ ⚹ ∻Explanation∻ ⚹ The final surface area of the cuboid is 19576 cm², which is derived from the dimensions provided. ⚹◊What is the formula for calculating the surface area of a rectangular cuboid?⍭ Generate me a similar question◊
