12 mm tall front face 8mm wide 10 mm long 15 mm tall side face
What is the surface area of the rectangular pyramid?
(1 point)
To calculate the surface area of a rectangular pyramid, we need to calculate the area of each face and then sum them up.
Front face:
Area = 8mm x 12mm = 96 square mm
Side face:
Area = 10mm x 15mm = 150 square mm
Since the rectangular pyramid has 1 front face and 3 side faces, we need to calculate the total surface area by adding up the areas of all 4 faces:
Total surface area = 96 square mm (front face) + 150 square mm (3 side faces)
Total surface area = 96 square mm + 450 square mm
Total surface area = 546 square mm
Therefore, the surface area of the rectangular pyramid is 546 square mm.
