For a project, Gabrielle made a model of an Egyptian pyramid. The square base has a side length measuring 10 inches. The pyramid is 12 inches tall.

What is the surface area of the model?

240 square inches
260 square inches
340 square inches
360 square inches


Answer :

340 I’m pretty sure
10x10=100 which is the base
12x10=120
120/2=60
60x4=240
240+100=340
