What is the surface area in square millimeters of the triangular pyramid?

alukav5142 [94]

Answer:

31 mm² is the surface area.

Step-by-step explanation:

We know that:

Surface area of triangle = 3(1/2 x 4 x 4) + (1/2 x 4 x 3.5)

Work:

3(1/2 x 4 x 4) + (1/2 x 4 x 3.5) mm²
=> 3(2 x 4) + (2 x 3.5) mm²
=> 24 + 7 mm²
=> 31 mm²

Hence, 31 mm² is the surface area.
