8 cm

144 cm^2

Step-by-step explanation:

The formula for a triangle is (L x W)/2. We plug this in so our first two sides are 24 and 24 square centimeters. The top side is 10 x 4, or 40 cm. The bottom side is 8 x 4, or 32 cm. The back side is 6 x 4, or 24 cm.

24 + 24 + 40 + 32 + 24 = 144 square cm

= 144cm²

Step-by-step explanation:  4x8 =32

                                               4x6= 24

                                               4x10= 40

                                                 8x6=48

      add 32+24+40+48 =144cm²
