Asquare pyramid has 2 m sides on the base. each face is a triangle with a base of 2m and a height of 1.5 m. explain how to find the surface area.

Surface area = 10m^

Area triangle  :  Half of the base multiplied by the height

half of  2=1

1x1.5=1.5Aarea of 1 triangle

the pyramid has 4 faces      4x 1.5=6m (lateral area)

base area    2x2=4m

total surface   6m+4m=10m

8 2/3 is the answer

step-by-step explanation: just use a calculator

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
