4. What is the number sentence? The side of the square is 4 cm The surface area of the plastic ball is 2
(2LW + 2LH + 2WH = n ) The slant height of the pyramid is 6 cm. 826 cm2
5. What is the solution? Surface area of a square pyramid = Area of
(2 LW + 2LH + 2WH = n 2 (52 x 30) + base + 2SL square units
2(52 x 25) + 2(30 x 25) = n 2(1,560) + where, S is the base side length and L is the
2(1,300) + 2(750) = n 3,120 + 2,600 + slant height of pyramid
1,500 = n Area of the base = (4 ×× 4) = 16
7,220 cm²) => Area of the base is 16 cm2
6. What is the answer? Surface area of a square pyramid = 16 +
(2 ×4 × 6)
( There are 7,220 cm² of wood needed
= 16 + 48
to make a crate. )
= 64
The surface area of the square pyramid is 64
