Question

Find the total surface area of this cuboid.
Height=4.8
Width=3.1 cm
Length=7.2 cm

Answer 1

To find the total surface area of a cuboid, use the formula SA = 2lw + 2lh + 2wh. Plug in the given dimensions to calculate the surface area.

Step-by-step explanation:

To find the total surface area of a cuboid, you need to calculate the surface area of each face and add them together. The formula for finding the surface area of a cuboid is SA = 2lw + 2lh + 2wh, where l represents the length, w represents the width, and h represents the height.

Given the dimensions of the cuboid:

• Height (h) = 4.8 cm
• Width (w) = 3.1 cm
• Length (l) = 7.2 cm

Plug these values into the surface area formula:

SA = 2(7.2)(3.1) + 2(7.2)(4.8) + 2(3.1)(4.8) = 44.64 + 69.12 + 29.76 = 143.52 cm²

Therefore, the total surface area of the cuboid is 143.52 cm².

Answer 2

• 143.52 cm²

Step-by-step explanation:

At = 2*(h×w + h×l + w×l)

= 2*(4.8×3.1 + 4.8×7.2 + 3.1×7.2)

= 2*(14.88 + 34.56 + 22.32)

= 2*71.76

= 143.52 cm²
