Answer:

461.02

Explanation:

2 × ( (12.3 × 4.3) + (12.3 × 10.7) + (4.3 × 10.7)) = 461.02 m^2

Answer:

461.02 M^2

Explanation:

A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

SA = 2lw+2lh+2hw

2LW = 105.78 M^2 ( 52.89* 2 )

L= 12.3 M^2 , W = 4.3 M^2

LW = 52.89 M^2

2LH = 263.22 ( 131.61 * 2 )

L = 12.3 M^2 , H = 10.7 M^2

LH = 131.61 M^2

2HW = 92.02 ( 46.01 * 2 )

H = 10.7 M^2 , W = 4.3 M^2

HW = 46.01 M^2

SA = 2lw+2lh+2hw

SA = 105.78 M^2+ 263.22 M^2 + 92.02 M^2

SA = 461.02 M^2
