Oak park middle school science classes constructed a plastic crystal by combining two right square pyramids, as shown in the diagram. each triangular face has a height of 6 inches and a base edge length of 10 inches. to determine how much sealant they will need, the class calculates the surface area of the figure. which of the following is the surface area of the combined firgure? a.340 square inches b.240 square inches cc.680 square inches d.170 quare inches
nobody answers the freaking questions man
(B) Area of a triangle = bh/2=10(6)/2=30 There are 4 congruent triangles in each pyramid. so Surface Area of the crystal = 30x8=240
ohh ok i get it thank u
