In the pyramid there are 3 triangular surfaces each with height(say h) and base with each side of equilateral triangle of 10√3 cm. Therefore total surface area = area of equilateral triangle + surface area of each triangle
√3/4 * 10√3 * 10√3 + 3 * 1/2 * 10√3 * h = 270√3
300√3/4 + 30√3*h/2 = 270√3
h = 12 hope it is helpful mark me as brainliest
